Barb - my points will be floating. the picture below is my test piece, but imagine the purple extends much larger and the beige is the background that would encompass the purple on all sides.
If I understand correctly, you don't want to seam the main fabric (purple, in your example).
Can you seam the background (cream) fabric? It would probably be easier to cut your zigzag edge on the purple and fit in triangles of cream than to have two zigzag strips and try to fit them together.
