The collage looks best printed as a 16 x 20 on metallic paper, on metal or as a gallery wrapped canvas. If choosing the gallery wrapped canvas don't use this photo. Use the next one otherwise the photos will wrap around on the sides of the canvas. (Gallery wrapped canvas means the canvas wraps around the sides so the photos along the outside of the heart will not be visible on the front of the canvas but partially on the sides of the canvas if use this photo collage. Because of this I added the next photo of the collage specifically for gallery wrapped canvases. You will notice it has more black space. This way photos will not wrap on the sides but be fully visible from the front).
This is formatted for printing as a gallery wrapped canvas. Best size is 16 x 20 although you can print as an 8 x 10 gallery wrapped canvas also.
