My friends and I made king sized double wedding ring quilts a couple of years ago. Guess who got to do all the bindings?
I used the KISS method(keep it simple stupid). sew slowly, you can use a walking foot, I didn't, then when you get to the point, just stop, needle down, pivot going the new direction and you're on your way. As I get closer to the point, I'm kind of pulling to make the edge do what I want it to. I realize this is not the proper way to do it, but I tried the right way and this worked great for me.
