This quick sewing project makes it a cinch to turn old jeans into a rugged book bag.
Zip the jeans and turn them inside out. With a pair of fabric scissors (a parent's job), cut off both jean legs 3 inches from the crotch. Set aside. Next, fold the cutoff jeans, matching up the side seams as you would to press front and back leg pleats.
Using a sewing machine (or a close, even hand stitch), sew closed each leg opening 1 inch from the cut edge. Trim the denim 1/2 inch from the stitching.
Turn the jeans right-side out. For a handle, thread a cotton belt through the belt loops and tie the ends together.
