My mom taught me how to Hem pants for my husband as they are always too long for him. Dress pants make me nervous to hem but it actually was pretty easy. I first had to cut off about an inch at the bottom because we had to bring it up about two inches. Once we cut that excess off we ironed the bottom exactly where we wanted the new bottom. We pinned it all into place at the very bottom so it wouldn’t shift around as I attached the hemming tape. Instead of buying the iron on tape , I got the kind that needed to be ironed on so it would last. It looks like ribbon but you sew it onto the bottom of the pants only to the end that was cut. I did that by using the sewing machine all the way around. Then I was ready to make the final stitch, I pinned everything back around the new taped end and the pant legs and carefully hand stitched an invisible stick all the way around.
