With Valentine's Day in mind, we tried it with a cupid silhouette cut out of contact paper. I literally traced this one from my screen.
We used the Parents Easy Squeeze Paints. [These paints have received terrible reviews on Amazon, but I don't think they are that bad - that being said, my expectations of products marketed for children are really low.]
Here is the final masterpiece. The paint did bleed under the contact paper (changing Cupid's figure) but she enjoyed making it.
Afterwards we enjoyed this...
