My mom made several small denim quilts for my sister's wedding. They were used to cover hay bales for seating. She also made some larger round ones to be used for table coverings.
What she did was "ice dye" some white fabric and use squares of that to lighten up the pieced top, and then used it for the backing. She also used lighter weight pants--dress pants, etc. Made it not quite as heavy as an all-denim quilt.
The squares were cut 6" squares, and there are 7 across and seven down (so 49 squares). It's not heavy at all.
I took a photo, but it doesn't do it justice at all :/
