I always measure and mark with a pencil where to stop stitching before turning the quilt for the next side. I use 1/4" seams so I mark 1/4" from the edge, stop with needle down and take several stitches backwards. When folding the binding up I am extremely careful the corner forms a perfect right angle and the folds are exactly matching. When i am ready to start down the next side I start with the binding under the presser foot and backstitch to the edge then start forward again. IMHO a walking foot is necessary for good results. Hope this helps. I also like the ladder stitch for attaching to the back.
