Quick Summary

Everything you need to know about the knitwear sampling process, from creating a tech pack to approving the final sample.

The sampling stage is where your design comes to life. For knitwear, this process is particularly nuanced because fabric structure and garment shape are created simultaneously during the knitting process, unlike woven garments where fabric is cut and sewn. This guide walks through the complete sampling process from tech pack to final approval.

Step 1: Preparing Your Tech Pack

A good tech pack should include:

The more details you provide, the fewer sampling rounds you’ll need.

Step 2: Yarn Selection

Your choice of yarn dramatically affects the final garment. Consider:

FactorImpact
Fiber contentHand feel, care requirements, cost
Yarn countFabric weight and drape
TwistDurability and stitch definition
Dye methodColor consistency, minimum dye lots

We maintain relationships with major yarn suppliers to source the right material for your design.

Step 3: Gauge Selection

Gauge determines the fineness of your knit:

Your gauge choice affects production time, yarn consumption, and final garment weight.

Step 4: Sample Development (7-10 Days)

Once the tech pack is finalized, here is what happens:

  1. Pattern programming: Your design is converted into machine instructions
  2. Yarn preparation: Selected yarn is prepared and tested
  3. Knitting: The garment pieces are knitted on computerized machines
  4. Linking: Pieces are joined together using specialized linking machines
  5. Finishing: Washing, steaming, pressing to achieve final dimensions
  6. Quality check: Inspection against your tech pack specifications

Step 5: Sample Review

Check these key points when reviewing your sample:

Fit
Does it match the spec sheet measurements?
Hand feel
Does the fabric feel as expected?
Stitch quality
Consistent tension, no dropped stitches
Color
Matches your PANTONE reference
Finish
Clean seams, proper edge finishing

Step 6: Revisions and Approval

Most collections require 1-2 rounds of sampling revisions. Common adjustments include:

Frequently Asked Questions

Common questions about manufacturing guide.

How long does knitwear sampling take?
Standard sampling takes 7-10 days from design confirmation. The process includes pattern programming, yarn preparation, knitting, linking, finishing, and quality check. Full sampling guide.
What should I include in a knitwear tech pack?
A good tech pack includes a flat sketch (front & back), size spec sheet, yarn specifications, stitch details, color references (PANTONE codes), and trim details. The more detailed your tech pack, the fewer sampling rounds you'll need.
What is the difference between cut & sew and fully fashioned knitwear?
Cut & sew knits fabric panels then cuts and sews them like woven garments. Fully fashioned knitting creates each garment piece to shape on the machine, reducing waste and producing cleaner seams. Fully fashioned is higher quality but slower to produce.
