I am not a clean person by any means, but I have a little phobia about messy art products, especially in the hands of my daughter. In order to ease us softly into art, we would do a project that actually isn't messy.
Theme: Art & Music
Materials: Wax Paper, finger paint, newspaper or something to cover your work surface (just in case)
How To: Put a few globs of different colors on top of a piece of wax paper and cover with a second piece. Have your child spread the paints around just as in regular fingerpainting. M loved watching yellow and blue mix to create green.
