Printing The Unicorn

You will need a printer with A4 size paper or similar. I downloaded the image from clipart-library.com. Then I used Poster It to create the poster of the image. Print the images and tape them together to create the image.

Tracing The Image

Place the poster on the polystyrene, and with a pin needle start tracing. Double check once you finished, and make sure you got it right. For the next step, simply draw with a black marker over the traced lines.

Start by painting the unicorn shape with white primer ( acrylic paint ). When the primer dried, then you can continue painting the colors.

Paint the unicorn shape in the desired colors. Be creative and pick some happy colors, kids love them. Let the paint dry well before applying the next layer. The paint I always love to use and I’m happy about it’s the patio paint from DecoArt.

For the black contour, you can also use a black paint marker. The paint marker usually melts the polystyrene. Used on top of the paint, never created any issues though. It’s a lot easier and faster.
