We purchased enough Wonder Clips to go all the way around a quilt. We lay the quilt out on our cutting table and smooth out the outside 8" or so. Then we lay the binding on the edge of the quilt smoothing it but not stretching the edges. We clip the binding to the quilt edge. We go all the way around it arranging the quilt so we have that flat 8" edge to work with. We arrange the corners just as you would stitch them. By doing this we are also able to go back and rearrange the border so none of the joining seams end up in a corner. Haven't had trouble with wavy borders.
