Make lily petals and base three days in advance. Tint gum paste deep blue. Use 9 in. fondant roller with pink guide rings to roll out gum paste 1/16 in. thick. Use lily cutters from set to cut six wide petals and 12 narrow petals. Store under storage board flap until needed.
For wide petals, working one petal at a time, use lily cavity (#8) of flower impression mat and instructions from gum paste flower cutter set to imprint petals. Use narrow end of veining tool to score center vein. Use knife tool to trim ½ in. from bottom of each petal. Pinch cut ends to shape. Let petals dry overnight on large convex section of wave flower former dusted with cornstarch.
For narrow petals, add details as for wide petals. Place six leaves on convex section and six leaves on concave section of wave flower former dusted with cornstarch. Let dry overnight.
For flower base, roll out remaining deep blue gum paste 1/16 in. thick. Use small rose cutter from set to cut out one shape. Let dry overnight in large flower forming cup dusted with cornstarch.
