The Sweater Worksheet is an integral part of the Cocoknits Method. In order to track the creation and progress of a seamless yoke, the knitter fills in the increases as instructed in the pattern, then knits from the Worksheet. The Worksheet also has areas for additional information such as the pattern name, size knitted, gauge, needles, and yarn used. The Cocoknits Sweater Workshop book does include one Worksheet you can photograph and store. The advantage of the Worksheet Journal is that it creates a history of all the sweaters you make, including any customizations and tweaks!
