OK, so I clearly had no idea what to make for my friend, and browsing through Knitty's old patterns, Sheldon seemed like the best choice. So I went out to buy some green cotton, only to find out that my LYS doesn't carry nice happy turtle colors in cotton. I ended up buying acrylics and CO yesterday.
This is the stage of completion today: one body, stuffed. Four legs, not stuffed. One third of a shell. Lots of yarn tails and tangles all over my bed. What can I tell you, knitting is messy.
