Swirly Paint Christmas Balls

Pretty and unique Christmas ball ornaments
These are super easy, inexpensive, and really pretty.
We used two colors per ball, but you could use more if you wanted to.
Just put about a tablespoon of each color in the ball and swirl it around until the insides are mostly painted.
Use your finger or better yet, some tissue, to cover the opening at the top and shake toward the unpainted parts to get the entire thing painted. The more you swirl and shake, the more the colors will mix, so don't do it too much (though I really like those parts the best).
Leave the tops off and let them dry. The package they came in worked really well for this part.
I'm thinking about trying some with some metallic colors next time. :)
