I always do my binding by sewing to the back first then bringing it to the front. I don't press the binding in half before sewing, and when I sew it to the front I don't pin except sometimes at the corners. For the front I use a zipper foot and just hold the binding in place with the edge right over the seam line. Sew a few inches, stop and position a few more inches and repeat. It goes very fast this way and always looks good.
