I love this idea! I've had to hem every pair of jeans I ever purchased for years; if I buy "short" they shrink up too short, so I have to buy regular length and hem. I too, loved the last sentence of this video, "...just kick 'em" - lol. Here is another video on the same subject, by Ron Appel of "Man Sewing". He discusses needle and thread requirements and shows how to cut the excess jeans material, as well as suggesting DMS stitches to finish the cut edges if you should so choose.
