I stitch in the ditch from the front. I position the wonder clips just like I would a pin. I tend to have my quilt back side up when I am pulling the binding fabric from the front to the back. I just make sure that the edge of the binding is covering the stitch line from where I sewed the front of the binding on. I put the clear part of the clip on the back of the quilt and the red side to the front. I wonder clip and sew. I remove the clips as I come to them, just like an ordinatry pin.
