I am painting my cabinets/cupboards and getting new knobs. I have decided for sure on oiled bronze (look black) circle knobs for upper cabinets, and cup pulls for drawers. My question is should I use the knobs for the bottom cupboards too or could I use The cup pulls for the bottom cupboards. The shape of the cupboards is throwing me off. I would use them the same direction they are on the drawers but near the corner on the cupboard not centered. Thanks in advance.
