The quilt police will arrest me for typing this but......it is my quilt and I'll do it my way. I cut my binding 2¼ inches
sew it on the front side of quilt ¼ inch seam allowance doing both right and left sides. I turn them to the back and hand stitch them down. I then do the same for the top and bottom. I do not miter the corners. I fold the raw edges in and hand stitch on the back side again. Find a way that works for you.:)
