DIY Shrink Plastic Buttons and Embellishments

Hold the shape gently in place using a pair of scissors or other metal tool on a heat resistant surface such as a cutting board or baking pan. Hold the heat gun a few inches from the shape and begin heating. Move the gun around to heat the entire surface of the shape. As it begins to shrink, the shape will curl up, however it should flatten out again as the shrinking is complete. You may want to press the shape flat while it is still hot for a few seconds using a flat object.
