Good for you and your treasure finds. I am so jealous. I hit our local thrift stores here locally and have come up with some good finds for pennies -- like a designer handbag or expensive clothes but have never found fabrics or quilt books. I wonder if it's because we have so many quilters in my area that quilt related stuff either never gets to the thrift shops or others beat me to it.
I'll keep looking. You'll have to show us the finished quilts (or even just the kits).
