Here is a closer view of some of the fabrics. There are polyester blends in there and some fabrics I can't identify except to say "coarse and scratchy". The solid blues are a thin chambray shirting fabric.
Look, it's Dumbo! Or at least part of Dumbo. The squares that look like pieced triangles are really "cheater" cloth fabrics.
I'm now having to make myself stay away from ebay because I keep wanting to "rescue" more quilts, quilt tops and quilt blocks. This is a whole new avenue for my quilting addiction!
