Marybeth, I have never seen 24" perforations but only 12" of which I have used dozens of rolls. You probably could have it custom made but that would be expensive unless you place a large order. Uline is a good place to look, but I would imagine you already know of them. Is there any reason why 12" perforations will not work? In all of the use by clients about which I am aware, I have never seen it tear along these perforations. Perhaps if there was a lot of movement of heavy objects on top of it, it would fail. But in general use I would imagine it will be fine.
