I immediately cast on for the next pair, using some Koigu PPPM that I bought last winter. I thought it was way too expensive to use while I was still learning sock knitting, but now I feel confident that I won't ruin it. And so far, I'm very happy with it - the colors are beautiful and the yarn is soft and lustrous.
I've also been knitting a sleeveless top, but I finished the back and took a good look at it, and I really don't think it's going to be a flattering garment on me. Too boxy and bulky. I knew I had to make it longer than the pattern or I wouldn't wear it at all, but I was afraid I was going to run out of yarn and stopped too soon (I'm NOT going to run out of yarn). So I'm still working on it sporadically and I'll complete it, but I'm no longer eager for the finished product.
