When you're using a transfer paper to apply a design or image to a surface, it's important to know which side of the paper to draw on. The top of the paper is typically where the design or image is printed, while the bottom of the paper is covered in a wax or adhesive that will attach to the surface you're transferring the image to. If you're not sure which side is which, test it out on a scrap piece of paper before starting your project.
