Well to be honest it will probably work the way you describe it.
But for myself. I am not sure I am picturing what you mean.
The blocks are a feathered star. And the border is a tone on tone
forest green?
Right?
If I understand you right it will probably turn out spectacular.
Have you laid it out to see on the floor or a bed? That always helps me.
Then I can see how it will look.
Good luck.
