I really hope that when LO gets a little older she'll want to do an art party. Here are some of my inspirations:

I love the cakeballs on the palette!

Seriously, these kids look like they're having a blast!

I'd also love to do a camping party as a sleepover.

Have you thought ahead about some fun parties you want to have for your LO? I just hope she agrees with me and loves the ideas too!
