This pattern is done in stockinette stitch, short rows, I-cord stitch and latch hooking for fringe, while color changes are made with fair isle and intarsia techniques. The size of your finished animal may vary depending on the size yarn that you choose, and the size needles. I use a heavy weight 3 ply yarn and size 2 needles for the horns and size 10 ½ needles for the main body parts. (You can double worsted weight yarn for a heavier weight) Yack-ity Yak is worked in approximately 120 yards of white (w), 100 yards of black (b) for his spots. His horns and hooves are worked in approximately 30 yards of light gray. I also used approximately 90 yards of light weight white and 15 yards of lightweight black 2 ply yarn for the skirting.
