1. Enlarge a clip art light bulb image and print out. (Shrinkable plastic will shrink down to ⅓ the size after baked.)

2. Lay the plastic sheet shiny side up on the image. Trace the outline and details with a black alcohol-based permanent marker.

3. Flip the plastic sheet to the rough side and color inside the traced lines with colorful alcohol-based permanent markers. Cut out the colored light bulb along the edge as smoothly as possible.

4. Place the cutout in a small dish or tray. Hold the heat gun like a pencil and turn it on. Wave it over the image in a constant waving motion until the plastic starts to shrink. The shape will first soften, curl up at the edges and then settle back down as they shrink.

5. Hot glue the shapes to a strand of miniature lights.
