duct tape will probably leave a residue. masking tape should work fine. a good sharp utility knife and a heavy straight edge. don't use a cheap utility knife with a single blade. you'll hate yourself. get either an olfa with a snap off or another kind that has cartridges so you don't have to replace the blade every few cuts.

good luck!
