David Page Coffin's career as a sewing expert, teacher, and writer began with a self-published how-to book about making custom shirts, which became a bestseller and led to an 18-year editor's post at Threads magazine, where both his sewing and publishing skills found a worldwide audience. Coffin is also the author/creator of the authoritative and bestselling sewing books Making Trousers for Men & Women and The Shirtmaking Workbook, hundreds of sewing articles, two Craftsy classes, and YouTube videos with hundreds of thousands of views. He has taught workshops throughout the United States and Canada and in the UK, appeared on nationally syndicated sewing shows, and been a featured host on various sewing bulletin boards and websites. He lives in Brookings, Oregon, with his wife Ellen. www.shirtmakingwithdpc.com
