Prepare 1 can gum paste; tint red. Roll out 1/16 in. thick. For each large flower, cut 5 hearts using largest Cut-Out; for each medium flower cut 5 hearts using medium Cut-Out. Place each heart on thin foam and ruffle top edge with ball tool.
Attach 5 hearts together in overlapping fashion, brushing overlapping areas with gum paste adhesive. Let large flowers dry in mini ball pan cavities dusted with cornstarch; use mini muffin cavities to dry medium flowers, let dry overnight. When dry, brush flowers with non-toxic purple chalk which has been grated in tea strainer.
