@Ann Sunny Sol Just an idea. You might have to move some things around so that the glass shows your china & stemware. but glass on either side of the sink might be pretty. It might make your arches more modern.
To make "custom" glass kitchen cabinet doors, just pry off the back wood part, have a piece of glass cut at the hardware store, attach with a heavy duty clear caulk. She used penny tile on the back of the cabinet.
