I have made 2 denim quilts. For both of them I just cut up squares and used regular quilting cottons on the back. They are not fancy but serviceable and easy to care for. They were for my 2 boys when they went off to college.
No batting though--they are so heavy as is.
Sorry about no pics--I don't own a camera or cell phone and don't know how to post if had the equipment.
