Star Backing

The star is about 72" square.

This is not the original design I had planned but after messing up several times, including cutting the pattern out backwards (no clue) this is where I'm ending up. And being almost done with this backing is really where I want to be. Why are backings so difficult?!...for me anyway. You can't see the top points in this photo because it's hanging over the back fence...no extra hands for pictures today.

Added: I forgot to say that this is AMH free star pattern, enlarged about 500%.
