my favorite use of gaff tape is at the end of the show, after strike when you have that one, two , three... or how ever many balls of gaff tape and have either a nice game of catch or better... dodge ball with gaff tape...but I have also used it to fix my friends sandals... she looked oddly at me when i gave her that over duct tape... but now she loves it too... making its way out of theatre... little by little...
