Guides
Fabric, weight and production notes for apparel buyers.
Short, practical notes on the decisions that sit behind a spec sheet — written from the way fabric actually behaves, not from a glossary.
These guides cover the decisions that come up before a bulk order: how fabric weight changes the garment, how sampling rounds are structured, and what to confirm before booking production. Each one is written for buyers who already have a tech pack or a reference sample.
