This Video Shows You How to Hem Jeans in About 15 Minutes.
With a little time and a sewing machine, you can sew jeans yourself and not pay someone else for it.
The Diva DIY video tutorial above shows a very easy way to hem jeans by folding the hem and stitching right under the original hem. Perhaps the best part of this is that you keep the original edge intact. However, this is probably best for straight leg jeans. (By the way, you can also skip the tailor on the hem of dress pants – with or without a sewing machine.)
