Help! I need to find way how to create gumpaste/fondant diamonds on a cake without cutters...(they cant be shipped on time!) I need them in vertical rows...

side note: any ideas on gumpaste simple palm trees on a side of the cake without cutters? Thanks!

I print off a design I find online. Example: Just google palm tree outline. There will be lots to choose from. Enlarge or shrink to your preference. Then cut with a sharp knife or pizza cutter. HTH
