My Magic the Gathering Deck (despit the fact that I barely play) is rat themed, and I added a bucnh of small plastic LEGO rats to my dice collection to use as counters. So I needed somewhere to store them! I found this rat pattern free online, but I can't find the original any more. I adjusted it slightly, and made my own new version:
She's hand-sewn together from wool felt.
I adjusted the pattern to have a zipper down the middle, and used a bright red satin for the lining. It's a little gory, but I love her!
