I have a goal for myself that each holiday we do one craft (at least) to celebrate, and learn about the upcoming holiday. This was our Easter project, lots of MESSY fun. Some shaving cream, washable paint, craft foam, bath tub, and eager toddler and we were set! She isn't normally one to get messy at all, but she LOVED this!
I actually forgot to take a photo of the finished project, but after the shaving cream, paint sit for a while you just scrape off the excess and it leave the foam (cut as eggs) "dyed."
