I recently made a denim quilt from worn out blue jeans. The quilt was put in the silent auction of the KCMGA Spring Seminar. The material for the quilt came from the legs of the jeans. The top and seams are left. What to do? Throw them out? Give up and cry? Nope, I make outdoor garden bags for them. Now, I suppose you could put some potting soil in these suckers and it would be pretty cute. I use them to hold random stuff like tools, fertilizer, my teeth (kidding).
Simply sew a seem across the bottom and use left over seams as straps.
