I have made several Jordy bags since finding this tutorial (I'll prove it when I get some pics!) but I can't get my straps to look good. They always have an exposed edge that frays and looks icky.
I need to get some stiffer interfacing, too.
I feel your pain, mnwild- I find straps difficult too- they're never very even and there's always a little bit showing- sometimes I just use something creative - like wide twill tape (like a thick ribbon) or webbing (like seatbelt stuff) to get around the whole turning them inside out etc- keep in mind that the stiffer the interfacing you use in the handles, the harder those little buggers are going to be to turn- especially if your handles are thin and long. good luck.
