The first sock is from a Cascade Kit. The sock is 100% cotton Cascade Elite and the pattern was called Lace Rib Socks. These are for me.
The second is a simple toe-up short row toe and heel using the basic pattern from Simple Socks Plain and Fancy with Regia Nation sock yarn for my mother, who is a Germanophile.
The last photo is newborn-size socks I made for a charity knitting event with my LYS group to raise money to clean up the SF Bay oil spill in the fall. I made 15 of them but only two were photographed.
