In this video, we learn how to hem a sleeve. First, turn your shirt inside out, then lay it flat. After this, grab the sleeve and fold it over to where you want it hemmed to. Next, place pins in the spots where you want your shirt hemmed, then go over the area with an iron. Next, go to your sewing machine and slip the sleeve around the platform arm. You will have to take the outer base off the machine to do this. Now, lower your needle and sew in the spots where the pins are, removing them as you go. When finished, turn your shirt out again, and you will be finished!
