I wonder how much a handmade blanket like that would go for on eBay....
Probably more hours than that...but I was really slow at first.
As for the eBay thing...hm, I dunno! This one had a LOT of flaws, but I suppose people who were good at such things could probably make a little pocket change that way. The materials are a little spendy, but I imagine there are place you can buy 'em in bulk.
