I recently found this http://www.quilterstv.com/video/1618...e-turnbow.html He's a bit dry to listen to but has a lot of good info.
I machine sew on to the front, turn and hand stitch to the back. I never used a walking foot before watching this. I have a small UFO that needs binding to finish so I am going to use my walking foot and 3/8" and see how it goes.
