We did my 7 year old's party from 1-3pm and my eldest daughter's 9 year old party from 3:30-5:30pm! I stuck with the same theme for both...
Cupcakes and Canvases
I had the privilege of using my professional artist step-mom, Susie, as the teacher. This was actually a very cost-effective party. I had a friend do the cupcakes, purchased all my table items and decorations at the Dollar Tree and used my 40% off coupon at Micheal's' to purchase the 8x10 canvases for $12 for 10 of them. And the ONLY place that (the right) washable paint is at is Target. My (handy) hubby used scrap wood out of his stash to make each girl their very own easel. They took the easel and canvas home as the party favor.
It was an exhausting day but I'll be doing the birthday party double header again in the future!
Didn't they do amazing with their paintings?
