Another denim quilt

This, my second completed quilt, is a single bed size.  It is made from what I term "found fabric" - all the scraps from other projects which I cannot bear to throw away, sewn together crazy quilt style.  As with the first quilt, I did not use a pattern for this.  The sashing is from a turquoise corduroy teamed with a brushed cotton check. 
The layers were fastened using buttons at the intersections of the sashing.  To me, this is the most practical method of quilting such large and heavy pieces of fabric.
