I just used some scrap yarn because I wasn't sure if I knew how to do the whole pattern. It turns out, I didn't. Can someone please tell me how to do a long tail cast on after the row has already been started? Or for that matter, just a long tail cast on? I tried the how to knit site and figured out how to do it that way, but I couldn't get tails at both ends (how it looks in the picture on Saartje's PDF) to save my life.
It did turn out pretty cute, I think, but the straps are completely improvised. If I do a whole pair, I'll choose softer yarn, but I want to be doing it correctly first.
