If you are anything like me, I find the PERFECT thing every 5 minutes. When brainstorming leads to chaos, it is no longer "a good thing" (Gotta love Martha).
Make a plan. Color outside the lines if you must,
but don't color over the masterpiece you already created.
In other words, If you want to incorporate something out of the box or not necessarily within the design you originally created, DO IT! Just be careful not to swing the pendulum the other way.
