I got a 2-for-1 on snuggies last spring! I can't talk my BF into having our engagement photo taken in the snuggies, though. He thought I was kidding!

Love the snuggie. In fact, I might mod mine. Some velcro at the top would be nice, so you can attach it behind your neck.
For a simple Christmas gift, I'd love to see a bottle of wine, a hand-made anything, or as others have said, anything from L'Occitane.
