How to hem a T shirt without it rolling at the bottom?

Question

I'm doing it by hand (I'm getting a surger when I can afford one). The best I can come up with is using iron-on hem tape, but I haven't tried it yet.

Answer 1

There is a product that looks like interfacing and comes in a  roll maybe 1" wide or less and irons on.  That is one option, but don't stretch the hem as you apply it.  A double needle also does a good job and you may want to use a stablizer.  Practice either on a scrap.

Good Luck

Answer 2

You could attach a ruffle or some other nice trim to the outside.
