1. Cut the legs off of small jeans to the length of a wine bottle plus 6 or 7 inches. Stitch the cut end together and tie with ribbons or raffia on the outside of the neck of the bottle so now you have a wine gift bag. 2. Cut squares of denim without any seams and then place 4-6 of them together. Stitch the edges closed with heavy thread or decorative stitching and you have potholders. 3. You can make book covers for school book if you have a large enough length of denim. Make it just like you used to make the book covers out of a brown grocery bag and use thread to tack the denim together at the fold inside of the book cover.
