I added the antique window frame in...   These are from an old house that was torn down ... the frame behind the walls that rames out for window openings.  A friend gave me several of them and each one has different predominate colors... this one seems to work best with the tan tones in the blocks.

Had a few remarks as to whether they are distracting or not.  They seem to add some interest to the paintings I've had them in so far...
