1. Find an old (but still in good shape) pair of sweatpants and put them on. The ones I used were huge on me! Have someone mark your hemline with chalk. Take them off and fold them in half lengthwise. Cut 1 inch below the hemline.
5. Next, measure around the bottom of the skirt and double that number. Cut out long strips about 3 inches wide from the legs of the sweats or other material. I chose to do a very quick ruffle with the legs of my fabric. Sew the strips together to form one long strip.
6. Pin the strips to the bottom of the skirt making a small (or large) pleat every 3 or 4 inches. Top stitch into place and you are done!
