I happen to come across a bunch of mouse pincushions at the thrift store, brand new, still in the wrappers for 25 cents! I bought a ton, and have gave them away left and right,LOL.
I also have one I made when I was a little girl out of felt. It is so ugly that its cute!
Let me see if I have anymore, and if I do, I'd be happy to send you one, and maybe you can copy it?
