One pair of old Jeans
Sewing Machine/ Serger
Step 1: Put your old jeans on inside out and pin. You might want to mark the pinned line with chalk. I pinned from the inside but you could also pin from the outside.
Step 2: Baste stitch the pinned line. Try out the jeans and if it is not the right fit, remove the baste stitches and try again. If it feels great, stitch over the baste stitches.
Step 3: Serge or zigzag stitch the edges.
Enjoy your new jeans! These look great with boots!
