I sew binding on by machine from time to time. I sew the raw edges of the carefully pressed double binding on the back of the quilt. Be sure that the quilt has been squared up. Then I press it from the back side using steam to be sure it is flat against the stitching. I sew the fold of the binding on the front being sure it just barely covers the first stitching. The mitered corners turn very nicely. Sometime I use a flange but not always. I do match my bobbin thread to the back. I am happy with the way it looks and sometimes speed it important.
