When you’ve settled on a size, you can add some effects to your image. Make it any color you like. I wanted to keep the original, so I chose not to use any. Before you finish, you may want to include crop marks and page position numbers. Crop marks make trimming easier, and I found them helpful. Page numbers help you keep track of which sheet goes where, but I chose not to use them, as they could have overlapped with parts of the image I wanted to display.
