I always machine sew my binding, no hand sewing for me. I sew it to the back of the quilt, then fold it over to the front and press. Then I use my zipper foot to sew it to the front. No glue, no pins. I hold it in place a few inches at a time and sew, stop and position a few more inches and sew, etc. The seam is always right against the edge of the binding on the back and looks good. I use a bobbin thread that matches the back of the quilt.
