Once we had a whole bag full of different items we went back to our house. I rolled out a huge piece of paper and let owen choose three colors of tempera paint that I squirted onto a palette (we use a plastic cookie tin lid that you can see in the table painting). I dipped the stick in some paint and made a mark on the paper. Owen got it right away and started experimenting to see what marks each object would leave. He also used his hands and feet (good thing I had brought a bucket of water out with us to wash up in). This is his finished piece.
The next day we decided to refinish a little table we have on our front porch that holds some potted plants. We used acrylic paints for this (if you have a paint eater stick to the tempera or watercolor until they understand not to eat it.). I gave O a couple colors and let him choose some brushes. He also decided to a pinecone and his hands. We sealed the table with a clear spraypaint after he was finished. Here's his table.
