Biker Boy from Son of Stich n' Bitch
This pattern is available in Debbie Stoller's new book, Son of Stitch n' Bitch. I really like this and am planning on making it for my husband anyway.
The only two downsides I can see to this as a KAL pattern, is that:
1) It's a big item (as opposed to knucks)
2) You'd have to buy the book (or find it in a local library) to get the pattern. Right now, it's going for $10.85 on Amazon.com (which isn't too shabby considering retail is $15.95)
Skull Socks of Fury from Hello Yarn
I dig these. I'd do them in black and pink. You, of course, could do them in whatever color you want. This pattern is also FREE. Hooray for free!.
