I got Elle (let's be honest...and me) a pottery wheel ($25 at WalMart). I have been wanting desparately to learn how to use a pottery wheel for years and years and hope to some day have a set up in our barn for a wheel, but in the mean time this will have to suffice.
Elle LOVED it. We were a total mess, which of course is always fun, and she was pretty good at it. (A little heavy on the water...)
Here's what the box looks like if you're interested. (again, I think it was $25 at WalMart...doesn't come with batteries though). I will say, the end product can't hold water though... so although they show a vase and a mug and plant pot... don't plan to make those if you want to use water in them. =)
