I had yarn left over from my 2010 TTL Mystery socks. It is Knit Picks Essential in Duchess Heather. I decided to use it to cast on some River Rapids Socks. It was a free pattern, but the blog no longer exists, so I'm not sure how much longer the pattern will be available.
Anyway, I cast on knit happily along, but realized I will not have enough yarn to complete the foot. I think I will be able to make just past the gusset decreases. I'm not ripping it out. Yes, I knew there was only two partial balls when I cast on. No, I'm not ripping it out. I'll just use the second ball to cast on the second sock. Hmmm, what color should I use for the rest of the foot?
