I saw this idea last year and we never got around to doing it, so this year we tried it out. All you need are potatoes and paint!
I just bought two baking potatoes and made sure I picked ones that were nice and oval-shaped. Cut them in half and then carve whatever designs you want into them. You don't have to cut very deep.
Then use the potatoes as stamps. We started out with four different colors, but then we started mixing colors which turned out pretty cool!
The beautiful thing about this project is that there's no clean up! Just throw the plate with all of the paint/potatoes away!
This was a great little Easter project. Easy enough for little ones but older kids could have fun with it too.
