Cowasocky is a cuff-down, heel-flap & gusset, intarsia-in-the-round sock with a 5-toed udder.
This pattern includes charts for making the sock in S, M, L, and XL sizes as well as templates and instructions for drawing your own cow patterns. Basic instructions for intarsia, intarsia-in-the-round, and links to other intarsia-related resources are provided.
There are two pdf files for this pattern:
Cowasocky.pdf includes the pattern instructions and charts for knitting the sock shown in the sample
Cowasocky Templates.pdf includes the instructions for drawing cow patterns and the blank template charts
The “B” should be on the right side and “D” on the left of the heel flap templates on pages 3, 6, 9, and 12 of the Cowasocky_Templates file. The schematic on page 1 has the “B” and “D” labels placed correctly.
