I happen to like the Sassy Stripes yarn. It's not WOOL, but it is very nice. I didn't have any trouble with the yarn "squeaking" or anything. I knit it on 5 DPNs in size 2. The pattern was Lion Brand's Magic Stripes sock pattern.
The sock turned out a little big, so I would switch to 2 circs, and go to size 1.
I also switched to using Queen Kanuna's Crazy Toes and Heels sock patterns and book. This is a toe up version and it is very nice.
Try it! I like it!
