Beautiful quilt, although it seems it was more work than you anticipated. My SIL has made several jeans quilts, backed with flannel - they are heavy, but very, very warm. All she did was sew squares of denim together in rows, then I think she tied them, but you could always use the quilt tack method - quilt a small design on the squares, like a star or you could tie it. My SIL also used the pockets for some of the squares which adds a unique touch.
