Keep transfer paper in its original packaging. This packaging is designed to keep the paper from losing its powder coating, while ensuring the powder coating does not transfer to anything else. Most transfer papers come as sheets packaged between thin parchment papers or in rolls like aluminium foil. When using colored transfer paper, store it in a dark closet or drawer when not in use. Exposure to light causes the colors to fade. Keep the papers in a dry place, since humidity can cause the powder to cake or clump.
When getting ready to transfer an image with transfer paper, secure the target paper to a hard surface with masking tape along all four edges. Secure the image to be transferred to the same surface along just the top edge. This holds the paper in place, but allows you to lift it up to insert the transfer paper and check your work. The powdered side of the transfer paper should be lightly wiped with a paper tissue to remove any excess powder. Carefully lay the transfer paper carbon side down between the two sheets and centered under the image.
Only the lightest color of transfer that still allows you to see the image is recommended. This reduces the chances of the transfer showing through paint, ink, or pencil. Avoid touching the transfer paper powder and then the clean paper, because smudging can occur. Trace the image with a pencil or pointed stylus. Press down firmly on the line, but avoid resting your hand on the paper, since the pressure will transfer your hand print to the clean paper.
Remove the transfer paper and the paper with the original image once the image is transferred. Store the paper back in its original container, since it can be reused later. Rub smudges from the paper with a large eraser. If you have a particularly stubborn smudge, use a small amount of rubbing alcohol on a cotton swab to wipe it away. Always test the alcohol on your paper before applying it to your projects. Paint, shade, or ink in your image as you normally would.
