1. Print out any picture or pattern (or draw your own on white paper). Cut around the outside of the pattern. Cut a piece of transfer paper slightly larger than the area to be doodled, and tape it to the surface. Tape the pattern over the transfer paper.
2. Using a pencil, firmly trace the pattern lines to transfer the design to the surface. Remove the pattern and the transfer paper.
3. Using a paint pen, trace the lines; let dry. Cure the paint by baking the piece in the oven, following the manufacturer’s instructions.
