Make sure the gumpaste or fondant is rolled thin to where you can almost see through it. This usually helps the gumpaste/fondant to ruffled when using a ball tool. I've tried making both of these flowers. The plumerias requires a slightly thicker petal, the hibiscus requires a thinner petal. I use a manual pasta machine to roll mine out. HTH.
