So here's the process: First, you need a cone shape, obviously. Last time, we used paper cones, that had been donated to me, for the cone shape. They were an awkward to hold size. I considered using flowerpots for a flat-bottom cone, but since everyone prefers sugar cones, I decided that's what these had to be. So we cut semi-circles out of cereal box cardboard, and curled them up into a cone shape. I hot glued them together, and the kids taped them for extra reinforcement.
We stuffed the cones full of newspaper. Then, we started making ice cream scoops, by balling up newspaper, wrapping the ball with a smooth piece of newspaper, and then taping the ball with a couple of 'belts' of tape, with extra tape to smooth any loose paper.
And everyone was happy!
