D: (Asking about Jasmine's guage swatch) But why was she knitting it round?
Me: She wasn't. It was a flat piece of knitting, but stocking stitch does just curl round. See, if you look at this side it's rows of tiny little half-moon bumps, and on this side it's rows of little 'v's. If you just knit backwards and forwards you get garter stitch, which has equal numbers of 'v's and bumps on both sides so it lies flat. It looks a bit like this, which is actually reverse stocking stitch, but with more space between each row of bumps. If you're knitting stocking stitch, instead of knitting backwards and forwards you knit one row and purl the next, so you get all the 'v's on one side and all the bumps on the other. That means that one side of the fabric is a bit bigger than the other side and that causes it to curl round.
D: But that's a good thing, right?
D: If you're knitting a stocking.
