Sorry to hear you are having problems. I only did one of these once before and my quilting buddy helped me. I just know we brought the binding up to the angle, then folded the binding (it kind of made an overlap) and that is the way I stiched it. I am sure there are other techniques. I would search on line for the Missouri Quilt videos on utube. They have a lot of videos and there may be one there that would help you. Good luck.
