For hemming I use tacky glue. It comes off in the wash but they also have glue that holds thru the washing I think it is called No sewing glue! This really helps at the last minute.

The cuffs and waists of cotton jeans that are beginning to fray can have their life prolonged by rubbing clear silicone glue into the fraying area. Once the glue has cured (about 24 hours) the jeans can be worn, washed, dried, and even ironed as normal.
Another jeans tip. Always wash and dry cotton jeans inside out. They will not fray as quickly around seams and pockets.
