Unless you're in a corner and can use the side wall to attach it to, or create an attachment that sets up the touchstone at a preferable angle.
Of course it doesn't necessarily have to be a wall either. Connect it to a desk drawer or the side of a bookshelf, as long as there is a material that's strong enough and depending on how strong the suction really is of course.
