I finally found a plumeria cutter, but the gum paste I am using, which is Linneas mix I bought at the local cake decorating store, keeps cracking as it is drying. HELP!!!! Ive gotten the hand of the flowers and need a lot of practice, but I am a perfectionist, and can't stand the cracking. I will post pictures soon.
Where are you located, and what are you rolling it on (cornstarch, powdered sugar, or shortening)?
Humidity (or lack of it) and what you roll your paste out on have a great deal to do with the way it behaves.
