W..
We did a paint your own pottery day when my daughter was probably 5 and we went on vacation to Kitty Hawk NC.
We painted a cake plate.
My mom's thumb print was the stem and leaves.
My thumb print was the middle of the flower.
My daughter's thumb print were the petals around the flower.
Then we wrote our names, the location and the date of our day around the side of the cake plate - like a boarder.
I LOVE it.
However, you could each do a regular plate or a bowl or a vase or whatever. I LOVE paint your own pottery.
I'm not sure how old your daughter is.... but the first time she was old enough to be included in mani/pedi's was probably the highlight of her life.
Have fun!
