Print the pattern(s). Place your printed animal pattern underneath the contact paper and trace it with a pen. Cut the inner section of the animal out.
Position your stencil onto the bowl, making sure its centered, and push out any air bubbles, especially around the stencil edges.
Use 2 mini paper plates, squeezing some paint out on one, dipping the sponge into the paint and dabbing it off a little. Use the second plate to dab off the remaining excess paint.
With a straight up and down motion to apply a thin layer (almost dry) over the stencil. Take a 1 minute break. Now add another layer to darken it up a bit.
Peel off the contact paper and set the bowl aside to dry. Repeat this process with all of your bowls (or mugs, plates, what have you).
