One could just sew the hems down but for non-sewers (you know who you are) I tested two different ways to bind the hem; I wanted options I knew could go through the wash.
1. Fabric-tac glue (the orange side).This glue is a little stinky to use but goes through the wash intact.
2.Therm-o Web Heat'n Bond
Ultra Hold Iron-on Adhesive
(the green side).
Measure out a piece of the iron-on tape and iron it on the hem; remove the paper backing and fold the hem over and iron a second time.
That's it- you're done! Yay!
