My latest book (published in 2016), entitled Double or Nothing: Reversible Knitting For The Adventurous, jumps in where Extreme Double-Knitting left off, expanding on existing techniques and breaking a significant amount of new ground.
My first printed book, entitled Extreme Double-Knitting: New Adventures in Reversible Colorwork, has now been re-released. Previously published in 2011 under Cooperative Press, the new revision is an update to 2018 standards for a book that was beginning to feel a little dated. I hope you will enjoy all of the new content and updated patterns.
The Parallax collection is a 5-pattern booklet (4 scarves and a seat cushion) that has become one of my most popular printed items. It is a great introduction to double-knitting; although there is less detail in the instructions than my other books, the patterns are accessible and visually striking (and 3 out of 5 are beginner-level patterns).
