I started one with a girlfriend of my late son with denim blocks mostly from old jeans. I bought some new denim pieces but washed them a few times so they wouldn't bleed on to the doilies. The 2 split up and I never got it finished before he died. I had it out a while back and hadn't realized how heavy it was so I am considering just using a flannel backing or even one side could be doilies and the other could be a rag quilt with the frayed denim. It seems like it should go on my to do list again.
