If you like the look of the binding being brought to the back , consider machine stitching in the ditch on the top side . Bring the binding to the back , but secure the binding position using a thin strip of wonder under or heat and bond light . They do sell a roll of 1/4 inch fusible in the notions isle at Jo ann's if you don't want to cut your own. I fuse the binding on the back just past the stitching line you made stitching the binding on in the first step( about 1/8 inch). This ensures you will catch the binding on on the back side, when stitching in the ditch on the front. I find at this step I have better success without the walking foot , just using a SID foot if your walking foot does not have a SID foot. I find the fusible to be faster than the elmers glue method to secure the binding position.
