This is very cool and I bet will be super cozy and durable! You could use a poly batting that has a lower loft and then tie the quilt instead of quilting it. Maybe a dark blue or dark gray yarn…knotting at the corner of each square or the corner of each block. You could even do a super lightweight flannel backing. You'll need a heavy needle and probably a thimble. A binding in a dark paisley would complement all the different denims. Ok, add this to my "would like to try this" list. What a super great quilt!!
