How do you hem pants without a sewing machine?

Without a sewing machine, there's a couple different things you can do. If you have an iron, you can try fusible, interfacing webbing. This product is basically an adhesive that melts as you iron it. Fold the pants underneath at your desired length and iron them using the adhesive. If you're in a rush, you can also try double sided tape. To use this method, fold up your pants underneath and tape it up using the double-sided tape. The nice thing about both of these methods is that it's a temporary hem, so you can always let the hem back down.
