Fiddle Knit's Dance All Night Slouch Socks, and you can get the pattern from Knit Picks for $1.99. It's a fun pattern, but it does require some knowledge in sock knitting before tackling it. As I have mentioned in my project details on various sites, it does include the evil p2tog tbl decrease. Even though there is a way around doing that decrease (p2tog, take stitch of right needle, turn it clockwise, and put back on right needle),
Don't let that keep you away from these fun socks. Knit in worsted weight yarn, they are a fairly quick project. I used the suggested yarn, Knit Picks' Chroma Worsted.
