No, we didn't get another live animal. In fact, this one won't even be staying at our house; he's a gift for a co-worker.
I knit him out of Briggs and Little wool that I bought at my local yarn store All Strung Out.
He's knit in pieces (8 total by the time you count all the legs), then stuffed and seamed. This was my first time trying an applied i-cord - much thanks to Ashley for the instruction!
The best part about Sheldon is that, much like wee little puppet man Angel, his shell comes off.
