I've been meaning FOREVER to do this with my little peas, and I finally got around to it recently.
We used to do this as kids with potatoes, cutting a shape out of the raw half potato.
For this time, though, we used some old apples that had been sitting around,
and just printed with the shape of the apple itself.
Simply cut them in half, dip into a tray of paint,
and press onto paper.
Sweet Pea also wanted to use brushes and lids to make different kinds of marks.
You could also try using different kinds of fruits and vegetables,
or do like we did as kids and cut out shapes in the foods.
We used a big sheet of paper from a roll, so we can use it later as wrapping paper for a special someone.
