YOU NEED 1. Ruler or tape measure 2. Chalk for marking 3. Thread to match pants 6.
Trouble is, they're way TOO long.
Turn the pants inside out. Measure from your chalk mark to the bottom edge. If you have a sewing machine, you can stitch this down. Use the iron to make a light crease all the way around-where your hemline will be. You can try them on again at this step to make sure the length is okay and even all the way around.
