It's a classic kids art activity that I'm sure we have all done, sometimes its just good to get back to basics! For me this is one of the best process art activities you can do and kids of all ages seem to love it. I did it for the first time with my almost 2 yr old and the joy on her face every time we opened the paper was just amazing.
Sheets of paper
Paints - either in squeezy bottles or with brushes
I'm pretty sure this activity doesn't really need any explanation! You just splodge the paint onto the paper and then fold it in half. Open up the paper and you have got a beautiful, symmetrical butterfly pattern.
