When I do my binding I use a Walking foot and use Sharon Shambers on gluing the binding down. when binding is all sewn down I press the binding to the back , I hand sew the mitered corners first then sew the rest by machine a stitch in the ditch. when you do your folding at the 90 degree angle make sure you have about an 1/8" over hang when folded back down the straight edge of quilt.this gives you a little bit more for your mitered corner.
