Wonky Jacob's Ladder
What if I start by duplicating the block grid around the outside of the design?
This is too busy for me.
This might work with a different design but I don't think it suits this one.
The accent border does not pick up the rhythm of the design like I hoped it would.
This is pleasant and it works, but I don't like having the narrow border on the outside.
I like this better.
I think this has a bit more punch. So this is my final answer.
