Detailed T-Shirt Tech Pack -- 2

I have a new T-shirt concept ready to move from sketchbook to sampling, and I need a production-ready tech pack to guide the factory with zero guesswork. My main focus is the technical documentation itself—I already have the colour palette and styling direction sorted.

Here’s what I need you to build into the pack:

• Fabric specifications – fibre content, weight (GSM) and any finishing or wash instructions
• Size chart – graded measurements for the full size run, clearly laid out in both metric and imperial units
• Stitching details – seam types, stitch counts and construction call-outs, all labelled on front, back and side diagrams

Please supply the file in an editable format (Adobe Illustrator or equivalent) plus a locked PDF ready to email to the manufacturer. Clean vector line art, measurement call-outs, and a concise bill of materials should be included so the factory can cost and sample without further clarification.

If you have experience preparing tech packs for knit tops or T-shirts specifically, let me know—clear examples will help me award the project quickly. I’m ready to start as soon as I see a portfolio piece that matches the level of detail I’m after.
