Textile Sampling Process: From Swatch to Bulk Order

A textile or garment sample is much more than a small version of the final order.

Sampling allows the buyer and manufacturer to verify the product before committing materials, production capacity and money to bulk manufacturing.

Depending on the product, the sampling process may involve:

• Fabric swatches
• Yarn samples
• Lab dips
• Print strike-offs
• Sample yardage
• Development samples
• Fit samples
• Size-set samples
• Pre-production samples
• Production samples

Not every order requires every stage.

The appropriate sampling process depends on the product, complexity, order size and buyer requirements.

The central principle is simple:

Problems discovered during sampling are usually easier to correct than problems discovered after bulk production.

If you are still defining quality requirements, first see our Textile Quality Control: A Buyer’s Checklist.

1. What Is Textile Sampling?

Textile sampling is the process of creating or supplying a representative material or product so the buyer can evaluate it before bulk production.

A sample may be used to confirm:

• Material
• Construction
• Color
• GSM
• Width
• Hand feel
• Fit
• Measurements
• Printing
• Embroidery
• Trims
• Workmanship
• Packaging
• Overall appearance

The exact purpose should always be clear.

A sample made only to evaluate garment shape, for example, may not use the final fabric.

A sample made for final production approval should normally be much closer to the actual bulk product.

This distinction prevents one of the most common misunderstandings in sourcing:

Buyer assumes the sample represents final production, while the supplier intended it only as an early development sample.

2. Start With a Clear Specification

Sampling works best when the supplier receives clear instructions.

For a fabric development, the buyer may specify:

• Fiber composition
• Construction
• GSM
• Width
• Color
• Finish
• Stretch
• Intended use
• Performance requirements

For garments:

• Technical drawing
• Measurements
• Fabric specification
• Color
• Stitching
• Trims
• Labels
• Printing
• Embroidery
• Packaging requirements

If important information is missing, the supplier may have to make assumptions.

Those assumptions can later create unnecessary sample revisions.

Before requesting samples, buyers can use our How to Request a Textile Quotation: RFQ Guide to organize the technical and commercial information required by suppliers.

3. Fabric Swatches

A fabric swatch is one of the simplest and most useful samples in textile sourcing.

It allows the buyer to evaluate characteristics such as:

• Texture
• Color
• Surface
• Construction
• Thickness
• Stretch
• Hand feel

Swatches are particularly useful during the early sourcing stage.

For example, a clothing brand may ask several suppliers for:

180–200 GSM cotton/elastane single jersey suitable for premium T-shirts.

Suppliers can send several swatches before the buyer requests larger sample quantities.

This allows unsuitable fabrics to be eliminated without purchasing full rolls.

4. Fabric Hangers and Sample Books

Fabric suppliers often present materials using hangers, cards or sample books.

These can show:

• Available colors
• Fabric constructions
• Weight ranges
• Finishes
• Seasonal collections

They are useful for initial material selection but should not automatically be treated as proof that the exact same fabric is available for immediate bulk production.

Before ordering, confirm:

• Current availability
• MOQ
• Color availability
• Production lead time
• Final specification
• Whether the sample is stock fabric or made to order

A sample collection may remain in a supplier's showroom long after some qualities have changed or been discontinued.

5. Yarn Samples

For yarn sourcing, sampling may involve:

• Small yarn cones
• Yarn cards
• Lab samples
• Trial quantities

Buyers may evaluate:

• Fiber content
• Yarn count
• Color
• Appearance
• Twist
• Hairiness
• Package form

However, some yarn characteristics require laboratory testing or processing trials rather than visual inspection alone.

For example, a knitting manufacturer may need to test the yarn on its actual machines to determine:

• Running performance
• Breakage
• Fabric appearance
• Knitting efficiency

Therefore a visually acceptable yarn is not automatically suitable for every production process.

6. Lab Dips

A lab dip is a small dyed sample prepared to demonstrate a proposed color before bulk dyeing.

Lab dips are particularly important when a buyer requires a specific shade.

A buyer may supply:

• Pantone reference
• Physical color standard
• Existing fabric
• Customer-approved color sample

The dyehouse then develops one or more color options.

The buyer may respond:

• Approved
• Rejected
• Make lighter
• Make darker
• More blue
• Less yellow
• More saturated

Several rounds may sometimes be required.

Once approved, the lab dip becomes an important reference for bulk color production.

7. Evaluate Color Under Appropriate Lighting

Color can appear different under different lighting conditions.

A shade that looks correct under daylight can appear different under artificial lighting.

For important color approvals, buyers and suppliers may evaluate samples under agreed lighting conditions.

The key point is consistency.

Buyer and supplier should avoid situations where one party approves color under one condition and the other evaluates it under a completely different condition.

For critical products, instrumental color measurement may also supplement visual evaluation.

8. Print Strike-Offs

For printed textiles, a strike-off is a sample produced to evaluate the print before bulk production.

A strike-off may be used to approve:

• Artwork
• Scale
• Color
• Placement
• Repeat
• Registration
• Printing method

The buyer should examine both individual colors and their interaction on the actual fabric.

Printing the same artwork on different fabric constructions can produce visibly different results.

Therefore, where possible, the strike-off should use material representative of the final product.

9. Embroidery Samples

Embroidery should also be sampled before bulk production when appearance is commercially important.

Check:

• Artwork
• Size
• Position
• Thread color
• Stitch density
• Edge definition
• Backing
• Fabric distortion

Embroidery that looks good digitally may behave differently when stitched onto:

• Lightweight jersey
• Heavy fleece
• Stretch fabric
• Woven fabric

Physical sampling is therefore particularly valuable.

10. Sample Yardage

A small swatch may not be enough for garment development.

The buyer may need several metres of material to produce prototypes.

This is often called sample yardage or development yardage.

It allows designers and manufacturers to evaluate:

• Cutting
• Sewing
• Drape
• Stretch
• Washing
• Shrinkage
• Printing
• Garment appearance

The buyer should ask whether sample yardage is produced using the same process intended for bulk production.

Sometimes development fabric is close to the final quality but not identical.

If so, this should be clearly understood.

11. Development or Prototype Sample

In garment manufacturing, the first physical garment is often a development or prototype sample.

Terminology differs between companies, but the purpose is generally to transform:

Design + specification

into:

A physical garment.

At this stage, the focus may be on:

• Overall shape
• Construction
• Design feasibility
• Fabric behavior
• Proportions
• Styling details

The first prototype does not necessarily need to be commercially perfect.

Its purpose is to identify what needs improvement.

12. Do Not Expect the First Sample to Be Perfect

Complex garment development often requires several revisions.

For example:

Sample 1

Sleeve too long.

Sample 2

Sleeve corrected, but neckline needs adjustment.

Sample 3

Fit approved.

This is not necessarily evidence of poor manufacturing.

Sampling is partly an iterative engineering and design process.

What matters is whether:

• Comments are understood
• Changes are implemented correctly
• Versions are controlled
• Progress occurs between rounds

Repeatedly making the same mistake, however, may indicate weak communication or production control.

13. Fit Sample

The purpose of a fit sample is to evaluate how a garment fits the intended body shape or size standard.

Typical checks include:

• Chest
• Waist
• Hip
• Shoulder
• Sleeve
• Length
• Rise
• Inseam
• Leg shape

The sample may be evaluated:

• On a mannequin
• On a fit model
• Through measurements
• Through a combination of methods

Comments should be specific.

Instead of:

“Fit is not good.”

write:

“Reduce chest width by 2 cm and shorten sleeve length by 1 cm.”

Specific comments are much easier for the pattern and sample teams to implement.

14. Maintain a Measurement Specification

Garment sampling should be accompanied by an agreed measurement table.

For example:

Terminology should also be clear.

If buyer and supplier measure from different points, both may obtain different results even when examining the same garment.

Measurement methods should therefore be standardized where possible.

15. Size-Set Sample

After the base size has been approved, buyers may request a size set.

Instead of checking only one size, the supplier produces several or all required sizes.

For example:

• XS
• S
• M
• L
• XL

The purpose is to verify grading.

A medium-size garment may fit perfectly while the XS or XL versions contain grading problems.

Size-set approval can therefore identify errors before thousands of garments are cut.

16. Check Grading Carefully

Grading determines how the pattern changes from one size to another.

Problems can occur if:

• Chest increases too quickly
• Sleeve changes incorrectly
• Body length remains too short
• Waist-to-hip proportions are wrong

These problems may not appear in the original base size.

This is why high-volume garment orders often require more than simply approving one sample.

17. Pre-Production Sample

The pre-production sample, often abbreviated as PP sample, is one of the most important stages before bulk garment production.

Ideally, it should represent the intended bulk product as closely as possible.

It may use:

• Final fabric
• Final color
• Final trims
• Final labels
• Final printing
• Final embroidery
• Final measurements
• Final construction

The PP sample answers the question:

Is this the product we are authorizing the factory to manufacture in bulk?

For many orders, bulk production should not begin until the required approvals are complete.

18. Why the PP Sample Matters

Imagine ordering 20,000 garments.

If a logo is positioned 3 cm too low on the PP sample, it can still be corrected before full production.

If the problem is discovered after all 20,000 garments have been printed, the cost of correction becomes much greater.

The PP stage therefore acts as an important control point between:

Development

and

Bulk production.

19. Approved Sample or Golden Sample

Once the final sample is approved, buyer and supplier should retain a reference where practical.

This may be called:

• Approved sample
• Sealed sample
• Golden sample
• Reference sample

Terminology differs between businesses.

The important point is its function.

It provides a physical reference for:

• Fabric
• Color
• Fit
• Construction
• Workmanship
• Trims
• Appearance

Bulk goods can later be compared with this approved reference.

20. Mark Samples Clearly

Samples should be clearly identified.

Useful information can include:

• Style number
• Supplier
• Sample stage
• Version
• Date
• Size
• Color
• Approval status

For example:

Style: TT-2048
Sample: PP Sample V3
Size: M
Color: Navy
Date: 04 October 2026
Status: Approved

This reduces confusion when multiple versions exist.

21. Control Sample Versions

Version control is essential.

Imagine the buyer approves:

Version 4

but the production department accidentally follows:

Version 2.

The correct sample exists, but the wrong reference reaches production.

To reduce this risk:

• Number sample versions
• Date comments
• Identify approved versions
• Withdraw obsolete specifications
• Store approved files centrally
• Confirm approval in writing

This is especially important when discussions occur across:

• Email
• Messaging
• PDFs
• Spreadsheets
• Technical drawings

22. Give Written Sample Comments

Whenever possible, sample feedback should be documented.

Instead of relying only on calls, send comments such as:

Fit

• Reduce body width by 1 cm.
• Increase back length by 1.5 cm.

Fabric

• Hand feel approved.
• Color too dark.

Print

• Move artwork 2 cm upward.
• Reduce print width to 18 cm.

Trim

• Replace zipper with approved reference.

Written comments create a clearer history of changes.

23. Use Photos and Markups

Photographs can make technical comments easier to understand.

For example:

• Circle the defect
• Draw an arrow
• Mark the correct position
• Show measurement points
• Compare approved and rejected samples

A short image annotation can sometimes communicate more clearly than several paragraphs.

But visual comments should still be accompanied by precise written instructions when dimensions or specifications matter.

24. Distinguish “Approved” From “Approved With Comments”

Approval status should be unambiguous.

Possible statuses include:

Approved

No further changes required for the reviewed characteristics.

Approved with comments

Production may proceed only if specified corrections are made.

Rejected

Another sample is required.

Different companies use different workflows, but ambiguity should be avoided.

A supplier should never have to guess whether a sample was actually approved.

25. Sample Cost

Samples are not always free.

Possible charges include:

• Fabric sample fee
• Development fee
• Pattern fee
• Sample garment fee
• Printing setup
• Embroidery setup
• Courier charges

Some suppliers refund development or sample charges after a bulk order reaches an agreed quantity.

Others treat sampling as a separate service.

Buyers should clarify this during quotation.

Our How to Compare Textile Supplier Quotations guide explains why sampling costs should be included when comparing suppliers.

26. Sample Lead Time

Sampling also takes time.

A sample may require:

• Material sourcing
• Dyeing
• Pattern development
• Sewing
• Printing
• Embroidery
• Washing
• Testing

Therefore buyers should ask:

How long will each sample stage take?

Sampling lead time should be included in the overall product-development calendar.

A factory offering:

30-day bulk production

may still require several weeks of sampling before those 30 days begin.

27. Factor Shipping Time Into Sampling

International sampling creates another factor:

courier time.

If each round requires:

1. Factory produces sample
2. Sample ships internationally
3. Buyer evaluates sample
4. Buyer sends comments
5. Factory makes next version

several sampling rounds can significantly extend development time.

Digital approvals can help with certain details, but physical samples remain important for characteristics such as:

• Fit
• Hand feel
• Fabric construction
• True color
• Workmanship

Plan accordingly.

28. Test Samples When Required

A sample that looks correct may still fail performance requirements.

Depending on the product, testing may evaluate:

• Fiber composition
• GSM
• Shrinkage
• Colorfastness
• Pilling
• Tensile strength
• Tear strength
• Seam strength
• Abrasion
• Stretch and recovery

The exact testing program depends on:

• Product
• End use
• Market
• Buyer requirements

Sample approval and laboratory approval can therefore be separate decisions.

29. Wash Garment Samples

For washable garments, testing the sample after washing can reveal issues that are not visible when new.

Possible problems include:

• Shrinkage
• Twisting
• Color loss
• Print cracking
• Seam puckering
• Shape loss
• Pilling
• Fabric distortion

For some products, the garment should be evaluated both:

before washing

and

after washing.

30. Do Not Assume Bulk Will Automatically Match the Sample

This is a critical sourcing principle.

An excellent sample proves that the supplier can make an excellent product.

It does not automatically prove that thousands of bulk units will all match it.

Bulk production introduces:

• More workers
• Larger material quantities
• Multiple dye lots
• Longer production periods
• Machine variation
• Process variation

This is why sampling should be followed by production quality control.

Our Textile Quality Control: A Buyer’s Checklist covers these later stages.

31. Consider Top-of-Production Samples

Some buyers request samples from the beginning of actual bulk production.

These may be called:

• TOP sample
• Top-of-production sample
• Production sample

Terminology can vary.

The purpose is to confirm that real production matches the approved reference.

This is different from a PP sample because it comes from actual bulk production rather than pre-production development.

32. Shipment or Reference Samples

For some orders, samples may also be retained from completed production.

These can help with:

• Post-delivery disputes
• Quality comparisons
• Repeat orders
• Future development

If a buyer places the same style again six months later, the retained reference can help both parties understand the previous quality standard.

33. Be Careful With Substitute Materials

During development, a supplier may sometimes use substitute material because final materials are not yet available.

This may be acceptable for certain purposes.

For example:

Fit sample made in substitute fabric.

But the buyer must know this.

A substitute fabric may be useful for checking:

• Pattern
• Basic construction
• Measurements

but not necessarily:

• Hand feel
• Shrinkage
• Final drape
• Final color
• Final stretch

The sample's intended purpose determines whether substitution is acceptable.

34. Sampling for Stock and Deadstock Fabric

Sampling is also important when purchasing stock-lot or deadstock textiles.

In these cases, ask whether the sample comes from the actual available lot.

This is important because stock goods may vary in:

• Shade
• Width
• GSM
• Finish
• Roll quality

A generic sample from another production batch may not accurately represent the stock being offered.

Buyers interested in this category can also read our Deadstock Fabric and Textile Stock Lots guides.

35. Common Sampling Mistakes

Several mistakes repeatedly create problems.

Approving only from photographs

Photographs cannot reliably demonstrate:

• Hand feel
• GSM
• Exact color
• Stretch
• Fit

Giving vague comments

“Make it better” is not an actionable specification.

Changing several things without documenting them

This can make it impossible to identify which version was approved.

Beginning bulk production before final approval

This increases the cost of later changes.

Assuming early samples use final materials

Always confirm.

Failing to retain an approved reference

This can make future disputes harder to resolve.

36. Textile Sampling Checklist

From Sample to Bulk Production

A disciplined sourcing process may look like this:

Requirement

↓

Supplier Selection

↓

Quotation

↓

Fabric/Yarn Sample

↓

Color or Print Approval

↓

Development Sample

↓

Fit / Size Set

↓

Pre-Production Sample

↓

Final Approval

↓

Shipment

Not every order requires every stage.

But skipping necessary sampling steps simply to save a few days can create much larger delays if problems are discovered after bulk production begins.

Find Textile Manufacturers and Request Samples

Buyers can browse textile companies on TurkishTextile.org across fabric, yarn, garments, home textiles, accessories, machinery and other textile categories.

When contacting a supplier, clearly state whether you require:

• Swatches
• Sample yardage
• Yarn samples
• Lab dips
• Development samples
• Garment samples

You can also create a buying request describing your product, quantity and sample requirements.

If you are unsure how to structure the requirement, see How to Write a Textile Buying Request.

The more clearly the sampling stage is defined, the easier it becomes for both buyer and supplier to move from an initial idea to reliable bulk production.
