It's cheap, it's messy, and it's very fun (especially when you are 2!)
My little one really got stuck in doing this, so much so I've hidden the sponges for a few days so we don't have to do it every time it rains!
I got our sponges from Tesco, they were only about a pound and a pound well spent. We used some Galt poster paints for the colour and then drew round them in pastels afterwards.
Sorry I didn't get any photos of the printing in progress... messy hands!
