Difficulty: Medium Tools: • Large canvas (I used two 30x40 canvases from hobby lobby- they often do 50% off sales!) • Plaster of Paris • Notch floor trowel How I made them: • Start with a generous amount of plaster on canvas and use hands or trowel to spread and make textured design • Use trowel to make arched rainbow designs • Lay flat until dry (at least 24 hours)
