Just did this and wow am I ever glad I did! The pack 'n play looked virtually unused but the water told otherwise!! I used homemade laundry detergent, vinager and a bit of burts bees baby shampoo for a fresh baby scent.
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!
