Here's what I do.....I sew the binding on the back, flip it over to the front, press it, stitch in the ditch. I have a long 5 inch needle that I use like a stiletto--I set the needle down on top where I want the seam line and then I peek under and make sure the point of my stiletto needle is on the bottom seam line, sew and aim for the stiletto. When you look at the back side you see a thick line, but you can't hardly tell it's two seams unless I have a drink or two. lol
