Paint the surface of the rocks in white and let the paint dry fully.
Separate the plies of paper napkin, you’ll just need the top printed layer of paper.
Cut a portion of the napkin design that you want to add on to the rocks.
Apply a coat of Mod Podge on to the rock and press the prepared napkin on top. Place the rock on top of a sheet of wax paper to avoid it from sticking the surface.
Smooth out the paper around the rock. Press out any bubbles underneath gently.
Apply another coat of Mod Podge over top of the rock to seal the surface. Leave it to dry.
As an added option, cut a piece of fine gauge wire and wrap it around the rock, create a pair of loops to resemble bunny ears.
