Here is a great craft to do with the kids: Potato Prints! You can also have them make Ink Stamps!
Cut potatoes in half or thirds.
Draw desired design onto potato with the pencil.
Young children can carve their whole design with the pencil but if more detail is preferred, an adult needs to cut around the pencil outline.
Place paint in tray or paper plate in a thin layer.
Press potato design into paint and firmly press onto paper for impression.
