A tech pack is not “nice-to-have.” It is your instruction manual for making a garment the right way, the first time. When your tech pack is weak, the factory has to guess. Guessing causes the same mess every time: extra sample rounds, delays, wrong trims or colors, fit problems, higher costs, and stress on both sides. Below are the 10 biggest mistakes first-time brands make, plus simple fixes you can apply today.

What a Tech Pack Is (And What It Is NOT)
A tech pack is the factory’s step-by-step guide for making your garment. It turns your design idea into clear instructions: what materials to use, how to build each part, what measurements to follow, and how the final product should be labeled and packed. It helps the factory produce your sample and bulk order with less guessing.
A tech pack is a production document. It is NOT a mood board, a Canva mockup, a Pinterest collage, or a fashion sketch without technical specs. The core rule: “If a factory needs to interpret your intent, your tech pack is not ready.”
10 Mistakes to Avoid in Your First Tech Pack
1) Mistaking a Mockup for a Tech Pack
A mockup shows how the garment looks, but a factory can’t build a garment from “looks” alone. They need to know stitch types, seam allowances, and finishing steps to ensure the sample matches your design.
- Fix: Include technical flats (front + back) with construction callouts and a Bill of Materials (BOM).
2) Building a Measurement Chart Without Technical Skill
Defining points of measure (POM) incorrectly leads to multiple sample rounds. Don’t just give numbers; explain how to measure them (flat vs. around).
- Fix: Start with one base size (e.g., Medium), define POM clearly, and include tolerance (±). Sending a physical reference garment also helps the pattern team immensely.
3) Unclear or Incomplete Line Drawings
If your drawings are vague, the factory’s output becomes a guess. Details often missing include stitch types, rib placements, and closure labels.
- Fix: Use clean, black-and-white technical flats. If someone who has never seen your design can’t explain it from the drawing, it’s not clear enough.
4) Conflicting Information Inside the Tech Pack
If page A says one color and page B says another, the factory will guess. Confusion creates hard-to-fix mistakes in bulk production.
- Fix: Do a consistency sweep. Ensure style codes, color names, and BOM items match across all pages.
5) Only Including a Colored Drawing
Colored drawings hide technical details like seams and topstitching. Factories require black-and-white flats to see the actual “build” of the garment.
6) Not Managing Colorways Properly
Changing fabric color often requires changing thread, zipper tape, or button colors. If these colorway details aren’t organized, mistakes happen in bulk.
- Fix: Use a master tech pack with clear colorway addendum pages or separate files per colorway.
7) Not Stating Expected Bulk Quantity Early
Quantity affects pricing, MOQ, and lead time. If you hide this, the factory cannot provide an accurate price quote.
8) Forgetting Packaging and Label Requirements
Labels are part of manufacturing, not a final step. Missing care label content or polybag specs can delay your entire shipment.
- Fix: Include a dedicated page for label placement, hangtags, and carton marking requirements.
9) No Version Control or Revision History
Tech packs change. Without version numbers (V1, V2, etc.), the factory might use an old spec and order the wrong materials.
- Fix: Add a revision table on page one. Clearly name files: StyleCode_TechPack_V2_Date.pdf.
10) Sending the Tech Pack Before It’s Ready
Rushing feels fast but results in more questions and delays. A half-ready tech pack is the quickest path to a failed first sample.
Conclusion
Your tech pack doesn’t need to be perfect, but it must be clear. Most mistakes happen when the factory has to guess. Before sending, ask: “Can the factory make this without asking me any questions?” If yes, you are ready for production.
