[COLOR="DarkRed"]Well...depends how long you are talking about. usually just leaning 'em is fine unless they are super-thin.
But if they are seriously going into storage for a while, I actually hang 'em from a rod parallel to the floor.
I have also taken drum cases and converted them to cymbal cases by doing this: putting a threaded rod thru the case and then slipping a plastic sleeve over the rod, then puting my cymbals over the sleeve with a felt spacer in between...then sitting the case vertically.
But that's probably more info than you needed....[/COLOR]
