I sew to the back first, fold over to front...then I figure out exactly where I want the needle to hit on the binding, usually 1/16th from the folded edge. I use the stitch in the ditch foot and let the flange ride right along the folded edge of the binding and the needle set just inside the fold. I never pin, I sew straight through, and I am can bind a queen sized quilt in about and hour, including making the binding. This has come with practice...but it is the easiest and the sturdiest method I have found. If it is a child's quilt or one that will be washed often, I use this method. If it is a fancy quilt to be inspected, I will sew to the front and hand stitch to the back...but after method number 1, method number 2 sure seems like a real pain and sewwwwwwwwwww slow!
