Of course, it's not a stupid question! Depends on what you want to do with your flowers - generally, full, multi-layer flowers (that's how I think of them) like roses & carnations don't press very well unless you take them apart. single layer flowers like daisies & pansies are easy to get to lay flat. good luck and have fun :> If you are using a shadow box frame, fuller flowers that have been dried work nice.
