So, I played with the layouts. I decided to go forward with scrappy. But, the control freak in me likes having the blades in the corners uniform. I have decided to sometimes use light and sometimes dare in the corners to continue the scrappy feel. I have prepared my blades, there will be 16 12" plates, 16 16" plates and about 40 4.5" plates.
Here are some pictures of what I put together yesterday at sit and sew. I am really pleasantly surprised how forgiving and easy the plates are to put together.
