You can decide whether we should stretch your photo mosaic to a 2 cm or a 4 cm stretcher. Depending on which option you choose, 3 cm or 5 cm of the main picture are wrapped around the frame. Therefore, when choosing your motif, you should make sure that no important parts of the picture are close to the edges. If you do not want a part of your main image to be folded over, we will print the sides in white, black or mirrored edge – so your photo mosaic will be displayed completely on the front. For a photo mosaic on canvas, the main image is required in a 4:3 aspect ratio. If your main image does not have this format, we will cut it free of charge.
