I take that back. There are 400 plus blocks. I counted them. I presume it would have been 500 if you count what I sent off already. Sad thing is I didn't even buy them all. The people who run the place separated them into different bags. I didn't want to look like (more of) a freak hauling them out, but if I go back today and they are still there I'm going to snatch them all up. They seem to be all done with vintage fabrics. A few are current-ish. Some are made with poly and flannel. It's been a trip going through them all.
