I've been working on 12" Churn Dash blocks with a fussy cut center. When I finished the # of blocks, it looked a bit skimpy so I've added a brown frame completely around each block which really makes them pop. Now I want to add the actual frame to the piece to set it off, as well as the border. My question is...Is there a set width they should be? My brown frame is 1-1/2", I thought the cream colored frame should be maybe 2-1/2" and the final brown border maybe 4-1/2". Does this seem excessive or just about right?
