I have a tube! This is my first time knitting in the round. DPNs are fiddly and awkward, but I have about one inch of 1X1 ribbing and one inch of stockinette. I'm still pretty sure the sock is going to be ugly and full of gaps, it might be a bit too small for me, and I may never make the second one, but I'm okay with all of that as long as it's a sock.
The yarn is really nice. It's Knitpicks Swish Superwasher wool. It's a brown colour, I think called Truffle. I have two balls of it and I have no idea what I originally bought it for.
