In some cases, it's possible to trace an image without using tracing paper. One way to do this is by placing the image directly onto your painting surface and then carefully rubbing a pencil or other pointed object over the top. Be careful not to press too hard, or you may damage the original image. Another method is to use a photocopy of the image instead of the original. This will create a less-faint copy that can be easier to see while you're tracing.
