We do not sell The Colette Sewing Handbook wholesale ourselves. Retailers in the US can order it from either Brewer or Checker. Canadian retailers can order from Checker if Brewer does not service your area.
The book is published by Krause Books, an imprint of F+W Media. To order directly from the publisher, contact them here.
In Australia the book is available through Australian distributor Capricorn Link: +61 2 4560 1600
Non-US retailers outside of Australia should contact F+W Media.
