All images must be sent in PNG format with a transparent background and cannot exceed 13x19 inches(have a boarder of 0.25). You will need to select the size that fits the largest size of your image, whether it is length or width. If your image comes in and is not sized correctly (The background/canvas/artboard and image needs to be the same size. Example: image is 12x11, background/canvas/artboard should be 12x11 too even though it is transparent. If it is not done this way the image will print smaller then wanted.) we will only size it to the size you purchased. We will not manipulate your artwork in any way.
