My Chompy was knit on straight needles, because I have a natural hatred for double-pointed needles (or perhaps an unnatural hatred for them…) So I had to come up with a way to create the whole thing - a circle - on straights… this is what I came up with. Think of it like a pizza, or a pie. You’re knitting a triangle shaped slice of the pie, and they’re all joined up. There may be a little open circle in the middle - you can weave your ends in to close it up and hide it if it bugs you.
