The Sweater Worksheet is an integral part of the . 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 has areas for additional information such as the pattern name, size you knitted, gauge, needles and yarn used. The  book includes one Worksheet in the back which you can photograph, store, and print as a jpeg. The advantage of the Worksheet Journal is that it creates a history of all the sweaters you make, including any customizations or tweaks. This way, you end up with a whole collection of sweater patterns customized just for you – and if you decide to knit another, your worksheet is already filled out and ready to knit!
