This is what we did today.
We used these acrylic paints and real artist canvas frames.
Quinn painted Godzilla with bloody teeth (Ew. Not sure I want to know what "Zilly" had been eating). He's a big fan of Godzilla these days, although he's never seen any of his movies.
Riley went more for the abstract. Can't you see this on a museum wall? He was quite serious about his art. You can't see it, but he even has the paint texture on his art (although I don't think that was done on purpose, but hey, it works!)
Here are all of them together. Kevin's is the top left, a beach scene, and mine is the orange house. Look closely and you can see the texture on Riley's art.
The boys really enjoyed using the canvas-I think they really felt like real artists. We are going to hang them up in the hall, on our own museum wall.
