Preparing the Recycled Cardboard Art Activity
A large active world tray is my go-to for this art activity. Place it indoors or outdoors on a stand or table. Or use an art table with a protective table cover.
Next, set recycled cardboard pieces in the sensory tray. Protective packaging and egg filler flats are good choices.

Then pour paint into paint pots and mix in a little water to make it thinner. Add brushes, and set the pots around the cardboard molds. That’s it!!!
