I just made some flowers a week ago or so for a birthday celebration that got postponed. They were hard & dry. Stored them in a plastic container..not necessarily airtight. That’s not a issue if there “set”. If it’s not hot & humid, the plastic container or box is fine. Mine are stored in a cool, dry area. Personally, I wouldn’t store in the fridge because of possible collected condensation.
