A contrast seam is both a graphic line and a construction operation. The panel shape, stretch direction and thread tension must be developed together.

What to Define Before Sampling

Write the product decisions into the tech pack before cutting. This keeps the development conversation specific and separates confirmed requirements from development examples.

Example Development Specification

Example only: Define material, fit, trim and QC values as a development scenario. For example, a program may use a stated GSM, a named zipper or stitch, and a measurement tolerance such as ±1 cm. These are not laboratory-confirmed facts about the pictured product.

Sampling and QC Checklist

  • Confirm the approved material, hand feel and recovery.
  • Check measurements, symmetry and seam or artwork placement.
  • Review trims, closures and attachment reinforcement.
  • Record sample changes before bulk cutting.
  • Use the approved sample and tolerance sheet for bulk QC.
