It's a Knot Crabby of course. For teething. Made of old t-shirts. But not anywhere near the armpit part of the t-shirt. The down by the edge parts and have been thoroughly sanitized parts. Griffin attacked it, so I guess I'll make more. It's needs some design work, obviously, but I like the idea.
(PS: I do not know what happened to the color in the bottom picture. It makes it look like a depression-era teething solution where someone ties dirty rags together.)
