How to Trace Images 1. Print out your image (not a reflection) the size you want it on computer paper. 2. Lay tissue paper (the kind you put in presents) over it and trace the image with a lead pencil onto the tissue paper, just like with tracing paper 3. Using painter's tape, tape the tissue paper with the image in pencil where you want it on the cooler. 4. Using a Sharpie, trace over the pencil lines. Press firmly, and every inch or two go back over that section once or twice.
