Alicia Bay Laurel added an entry about Paint with acrylics:
What I love about painting with acrylics is that they are very forgiving. Whatever you don’t like, you can paint over—the paint is very opaque. However, you can thin acrylics with water and make them look like watercolors, too, and get those kinds of effects. Acrylics dry permanently on cloth, so they can be used as fabric paint. The colors are brilliant, the paints are cheap, and you don’t need super fancy brushes or thinners. And the whole mess cleans up with water!
