Cut a slit on the bottom of one of the pant legs. Now start ripping along the slit all the way up to the top of the leg, as far as you can go.
Continue cutting slits about 1 1/2 inch wide, and ripping them up the leg. You will need three, one for each of the headbands. When you get to the top, cut each strip of fabric loose from the pants, and trim off the bottom hem. Then cut a small piece off of one end, about 3/4 inch long.
Take the small scrap and fold it over the end of the headband. Then wrap it around the band and secure it with hot glue. Repeat for the other tip of the headband.
Next, take your long strip of denim. Place the tip of the headband close to the edge of the denim strip. Wrap the denim over the headband and secure with hot glue. Now pull the fabric at an angle and start wrapping it around the headband. Secure with small amounts of hot glue as you go.
Continue wrapping till you get to the end of the headband. Make sure you secure the end piece well. There you have it, a cute headband made from recycled jeans.
