Hi Deborah. I'm Cindy. If you cut off both legs from a pair of jeans, you can sew them together to make one long leg. Sew one end closed and stuff it with your choice of stuffing, Sew closed. Put it at the bottom of a door to keep drafts out in cold weather. You can also cut off the back pockets and use as coasters. I've also seen home made rugs from jeans. Cut long VERY THIN strips and start braiding. Add a drop of glue now and then to hold things together. Once you have jean braids, you can start making the shape of rug you want. And, again, glue every now and then. Good luck Deborah.
I have seen people make cute pillows out of old jeans
