This was going to be a post about our experience painting with tennis balls. But there's not much to say, because we never got very far.
I put some paint on a paper plate and Kay rolled the tennis ball in it, then bounced it hard onto the paper I'd placed on the ground. She bounced it one more time, then said, "It makes an ugly design." Then, "Can I paint with my feet?" Does all of our painting projects have to devolve into body painting? Apparently.
