Gather your cardboard tubes. If you use paper towel or gift wrap tubes, cut them into halves or thirds. You can cut TP tubes in half to use them for the babies. Next, paint some tubes white and some yellow, using a wide brush. The tubes for the sheep simply need a vaguely face-shaped black patch. Since the paint will take as much as half an hour to dry, you could do this step before getting the kids involved. An egg carton makes a nice, optional drying rack.
