I have both the Fons and Porter tool and the one demonstrated by Missouri Quilt Co. and I have never had any luck using them. The instructions are confusing with both and it seems like the ends never fit perfectly. Then I saw a video on YouTube that made it so simple. So, forget the binding tools! All you need to do is overlap the ends of the binding by however wide your binding strips were cut - e.g. if you use two and a half inch strips for the binding, then you overlap the ends by two and a half inches. Trim. The join the ends with a diagonal seam, trim the seam and finger press it open, and then finish sewing the binding to the quilt. Easy schmeezy and you get a perfectly smooth binding.
