I printed mine on watercolor paper to give it a more muted and artistic look. I wasn't positive my printer would handle the thick paper, but it did, YAY! I trimmed up the edge, but did want to leave some of the white paper.
I found a piece of scrap wood that made a nice background or frame, I sanded it, clear coated it, and simply tacked the print on with upholstery tacks. Use a small drill bit to start the holes so the paper does not get creased.
