From Our Workroom
Prewash cotton twill before you cut, the same way you'll wash the finished piece. Cotton can shrink slightly in the first wash. The raw 160 GSM unbleached twill needs that prewash most; the other unbleached weights are ready to sew.
Twill has a diagonal rib, so cut every piece with the grain running the same way, or the diagonals won't line up at the seams. Use an 80/12 needle on the lighter twills and a 90/14 on the 6.5 oz and 8 oz, and press with a pressing cloth so dark colors don't get shiny.
