You might want to try a small lap size quilt first. I've always wanted to try the Mock Cathdral Window pattern in blue jean fabric. You cut circles out of one layer of blue jean. You center a square of a different material in the circle just about touching the edge at the 4 corners. The blue jean circles are sewn together by the square edges. You can add a square of batt under the fabric square but you probably won't need it. There would be no heavy seams to sew through and you can easily add to it if you like how it's coming along. I've seen some really nice ones done with a layer of flannel in the center and the jean fabric circle edges allowed to fray. There is a tutorial on the net on doing a jean quilt this way.
If you're not in the mood....send them to St.Vincent or Goodwill.
