I have made a few denim quilts. I did not use batting with any of them because of the weight. The last one I made was for my daughter last Christmas, with just strips like a jelly roll quilt, and used a light weight blue and white striped fab. looked like (but wasn't) ticking. The first one I ever made I used the pineapple pattern, and blue bandana fab. for the corners, and used the blue chambray fab. for shirts for the back, that a friend gave me turned out great. I tied both of these because of the weight. I have also made one with frayed edges for each block, and colored fab. for the back. They are very washable, but I would suggest because of the weight if it is going to be of any large size to take it to the laundry mat and use their heavy duty washers.
