We were given a stool for the kid to decorate for a local arts and crafts store, and we decided to make it the only one actually done completely by a kid. It's friggin awesome.
She painted a good bit of it, then declared it done. Her dad and I filled in the negative space with more paint, covered it with clear coat, and turned it in. They didn't think it was the awesomest one ever, but I do. And that's what counts.
