Gaffers tape is woven cloth tape, made from cotton thread, it is not shiny like duct tape (reinforced vinyl), and thus does not reflect light.
Set designers and stagehands rely on this finish because it means that they can make repairs, secure cables, and hide things the audience shouldn’t see, simply by applying a strip of tape. It is almost invisible in most performance environments.
A tape that does not draw attention to itself and doesn’t reflect bright lighting has countless uses.
