When I read the rules for round 4 I immediately had vines and leaves and flowers in my mind.
So I added another plain green border and positioned some vines on it and looked at it and looked at it ....and tried to see some leaves and flowers...no, I don't like this idea any more..
So now this piece already hangs for more than a week on the wall.
What I'll probably try this evening are some yellow circles in different sizes, dancing on the 2 borders. Maybe that will work..
