Earlier this month I knit up a new friend for the little man: Sheldon.

Sheldon
He is knit from Knit Picks Shine in colourways Arbor and Leapfrog. The pattern is free from both Knit Picks (the link above) and Knitty.
Naked Sheldon
He has a really cute removeably shell, and that means there are lots of (free!) costume patterns for him.
Sheldon's Shell
The little man seems to like Sheldon, so he just might get a full wardrobe to play with too.
