Step 2: Decorate the shrink plastic
If you've selected the Ink Jet printable shrink plastic, you can print on both sides with your Ink Jet printer. Select and print any image you like. I've created coordinating prints on my computer, and printed both sides of 2 pieces of white Ink Jet shrink plastic.
Another choice is to use the Frosted Ruff 'n Ready clear shrink plastic, which can be decorated with acrylic paints, permanent markers, and colored pencils. There are detailed instructions inside the package. I've created an ombre effect by putting dots of acrylic paint onto the rough side of the plastic, and using a paintbrush to spread it thinly across the plastic.
