I just found a machine binding method with a faux piping. You cut two strips (if you usually cut your strips 2-1/2", you cut one 1-1/2" and one 1-3/4". Sew strips together, then turn them right side out. Match the edges, and press. This will give you a 1/8" faux piping. Sew on the back, piping fabric facing out. Join with whatever method you usually use. Then fold the binding to the front of the machine. Stitch in the ditch at the piping, mitering the corners as you stitch. I haven't used this method yet, but I've shared it with several quilting friends, and we are all planning to use it on our next quilt. I have a tutorial with pictures in .pdf format, so if you would like a copy, PM me.
