The knife edge binding looks good for the quilts that are hung and don't get washed too often. For the mitre corner bit couldn't one just after sewing the straight sides down on the back, the across ones could be folded at the corners at the 45 degree angle which would make a mitred frame on the back. A different idea for the gluing and ironing of the regular binding is one which I haven't tried but Judy who runs an online business in Australia told us she sews her binding on with fusible thread on one side and then irons it and the binding stays stuck on for easy handstitching without pins or clips. (Or machine sewing I guess.) I would imagine you would place it in the bobbin and then sew so that when the binding is folded over it meets the fusible thread there rather than where it left from if you get my drift.
