I will create factory ready tech packs with patterns and full size grading
Kenji Arch
About this gig
Acid wash is a chemical reaction, not a print - and a tech pack that ignores it will fail in production. I write tech packs the way the people who cut, wash and sew actually need them.
12+ years in Guangdong with my own factory and sampling room: streetwear, outerwear, denim and knitwear.
What you get:
- Technical flats with construction and finishing callouts
- Full measurement spec with tolerances, plus size grading S-XXL
- BOM and trims list, including hardware and wash notes
- CAD pattern and an optimised marker layout on the higher packages
- Wash and finish specification for vintage and acid wash programmes
Deliverable: everything a factory needs to quote and produce without a second conversation. The full package includes editable source files.
Not sure your design is producible at your target price? Start with the $100 Sample & Fabric Feasibility Review - I will tell you what is realistic before you commit.

Expert garment manufacturer | 12+ years in Guangdong, China. Own factory and sampling room, not a broker.
I take on production problems standard factories avoid: high-difficulty construction, acid wash, garment dye, complex finishing. Knit and woven, womenswear and streetwear.
Capacity 10,000 woven / 50,000 knit pieces per month, from 50 pcs per colour.
Every project starts with a $100 Sample & Fabric Feasibility Review: construction risk, fabric direction, realistic sampling plan. Samples, materials and shipping quoted separately.
Send me a photo and your target price.

FAQ
Will my factory understand your Tech Pack?
Absolutely. My Tech Packs are not just sketches; they are industrial blueprints. They include accurate measurements, BOM (Bill of Materials), Pantone TCX codes, and specific washing instructions (e.g., "Enzyme Wash 45 mins") that Chinese/Vietnam factories understand perfectly.
Can you ship the actual fabric swatch to me?
Yes! This is my unique advantage. If you order the Premium Package or the "Ship Swatch" Extra, I will cut a physical sample (Header) of the recommended acid wash fabric and ship it to your studio via FedEx/DHL.
Why do I need specific fabric for Acid/Vintage Wash?
Not all cotton can handle the chemical reaction. Standard cotton will tear or look "muddy." I specify Heavyweight French Terry (usually 380g-520g) with the correct yarn twist and reactive dyeing base to ensure the wash effect looks luxury, not cheap.
How do you handle shrinkage caused by heavy washing?
Heavy washing causes 8-12% shrinkage. In my Standard/Premium Tech Packs, I include a "Pre-Shrunk" grading allowance in the measurements, so your garment fits correctly AFTER the wash process.
I have a photo of a specific vintage hoodie. Can you match the wash?
Yes. Send me the photo. I will reverse-engineer the look by identifying the base fabric color and the chemical spray method needed to replicate that specific vintage texture.
