Forgot to take pics of this project in the "Before" stage - so here's a quick pic of the finished product:
All we did was paint cute happy faces onto cheapo terra cotta pots with acrylic paint. Then spray painted them with clear spray paint (otherwise the paint will run/disapper when you water the plants). Fill the painted pots with dirt and sprinkle generously with grass seeds. Water, water, and water some more...and a few weeks later your cute little happy faces have cute spiked hairdos! I think I need to make one of them into a mohawk.
