Extreme Double-Knitting will soon be out of print.
In 2011, this book was the pinnacle of my achievement in double-knitting. In 2018, it feels a bit dated. As the rights revert from Cooperative Press back to me, I am gearing up to release a revised and expanded edition of Extreme Double-Knitting, with updated charts, explanations, and several redesigned patterns. This process will take some time, during which the physical and digital book will be unavailable. It is my hope that you will find the new version much more fulfilling and useful.
If you are still interested in buying the 2011 version, please feel free to visit the main Extreme Double-Knitting page, where you may buy copies until the links stop working.
If you are interested in finding out when the new version is ready, please join my EDK Announcement email list. Thank you for your interest and support.
