I have to make a 4 tier cake in September, to have gumpaste Plumeria/Frangipani cascading down all tiers. I have never, ever seen a real life Plumeria flower, so I don't know how big they are, and I did a search on Google images to see if I could see a pic with some kind of scale reference, but no luck. So could anyone tell me how big they are? Like, Hibiscus big, or Primrose small? I have a set of 3 cutters so I have to stay within those sizes, but I'm not sure which size would look good on the 4 tiers...

Plumeria are in between. About 1.5 inches, give or take, depending on how wide you open them after twisting the bunch of 5 petals.

Great, thankyou!
