Paint the cardboard egg cartons inside and out. Use fun colors like yellow, pink, red, purple and light blue. Let dry. When dry cut out and trim.
Cut slits in egg carton and fold downward to create petals.
Fold mini muffin liners in half, and in half again. Use a toothpick to carefully poke a hole in the liner, going through all layers, about 3/4" from the pointed tip.
Carefully poke the lollipop stick into the hole in one of the folded liners. Repeat three more times, using four liners for each flower. You can also just fold them in half and use two instead, which may be easier for younger children.
Grown ups should carefully poke a hole in the bottom of the egg cup. Insert the lollipop stick through the hole, bringing the egg cup flower as far up as it will go. They should stay in place on their own, but if you have any that are not cooperating, simple secure the lolli stick with a bit of tape.
