Playdough filled balloon. Did this for our road trip and for the little amount of effort it took to make it had a lot of fun value. I even played with it for a while like a stress ball. Make sure you get as much air out as possible, it will shape bet
I like the idea of using a tension rod between the two shelves for a curtain to create a stage for puppet shows or talent performances or hide things before company comes over! Plus I'm pretty sure everything here is from IKEA!
