They talked about Firebirds. They talked about Summer Sun. They talked about Summer Soltice. They named the sock Soltice Slip, but I don't know. I think this might be the true inspiration. What do you think? I loved making this sock! The pattern was easy to memorize and it was also easy to put down and pick up again! I must say, I did have to put it down a time or two to have a Berry Rainbow Sherbet break! Happy Summer!
