Yesterday was the first day we attempted to paint with watercolors.
I liked it a lot better than regular paint. Just as colorful, half as messy. Unless you count the potential for flooding, but if you keep the dipping water to a minimum, you should be all right.
We taped ours to newspaper so that it would lay flat. It was impossible to get off so I just cut around it.
And voila! Pretty coffee filter art for one and all!
