If you like running you’ll love this project! You can recreate comfortable and feminine track pants from your old and unfashionable ones. You will need old pants, scissors, sewing machine or needle and thread, iron. Use a pair of pants if you have them as a pattern. Make sure to leave about an inch for seam allowance. Use some ribbing for the bottom. Now you should fold in half and iron it flat. With right sides together sew around the bottom edge. Then leave about 1/2 inch over to sew the leg seam up. As you sew make sure to pull the elastic ribbing so it fits all the way through. The rest of the tutorial is here.
