8.5x11 printer paper is my favorite. You can find it in any office, school, or modern home. It makes no assumptions about line direction or grid size. And with entry-level origami techniques you can reconfigure it into mobile sizes. Then, when you realize what you wrote on it wasn't actually important, you can use it as an impromptu fly-swatter or dustpan.
