hiding canvas items?

I draw a large number of items on a canvas, and I am interested in toggling their display. For instance, if I uncheck a checkbox, all items with its tag will disappear, and they will reappear (rather than be redrawn) when I click the checkbutton again. Deletion and redrawing would take up too much time.

I suppose I could make them the same color as my canvas and lower them beneath everything else, but that approach seems particularly inelegant.

Any help in figuring out what I would intuitively expect to work but can't seem to make happen would be much appreciated.
