This is a very cheap and easy upgrade to a boring frame.  I had this painting in a simple black frame and it looked just fine where it was hanging before, but when I moved it into this grouping, everything was too much the same size-boring!

Rather than spend my afternoon chasing down an overpriced picture frame, I just mounted the existing frame on a bigger piece of wood painted to match the frame.

I started by cutting an old weathered piece of plywood down so that it was 2 inches bigger than the frame on each side.

This rough piece of wood works for the way I decorate, but you could easily find something more polished for cheap in a home improvement store and they will cut it to size for you.  This same method is adorable using a piece of beadboard.

Sand the wood down and paint it the same color as the frame – this is a good time to touch up the frame too if it needs it.

Once the paint is dry, put the art or photo back in, then attach the frame centered on the board.  I used hot glue because I want to be able to remove it later.

One hour upgrade; cost to me?  Nothing!
