Using the flower nail and a 2 in. square of waxed paper, pipe a tiny tip 101s petal, just half an inch long, narrow at center and curved at outer edge.
Try to maintain a continuous back-and-forth motion, moving hand out, then out again, as you press out a circle of overlapping petals.
Do three rows of petals, one on top of the other, making each row shorter than the last.
Fill center with tip 13 stars. Place on cake board and let dry.
