So, I decided not to use my original centerpiece idea. I don't think it would look right in my venue (the PB Zoo's) restaurant and think I should stick to the tropical/fun theme that the restaurant already has.
I stumbled across these and think they'd be perfect. FI likes them and even my conservative mother likes them. My only question: would this be something a florist could create or would I have to? I have no problem DIYing them but they'd probably have to be made the day of so the pineapple will keep. I would obviously do a few trial runs to see the status of the pineapple. I'd rather not do them the day of but I don't want icky brown pineapples, haha. Please keep in mind the flowers will be different (more tropical-y).

Thanks for your thoughts!
