I am making a denim quilt from denim dresses. I went to the thrift store and bought all the great looking dresses that were denim. Because there is more material, I can cut larger squares. 10 inch squares and I am backing it with a blue batik flannel. I'm making it rag so that I don't have to bind that denim or quilt the whole quilt. I just quilt each block as I go. I'm not using any batting. Once in a while one of the thrift stores around here has an 88 cent special on all clothes. That's when I picked up my denim.
