I've done some recently by just tearing it at the start the right width, tears off all the way round the same width, slightly messier but easier and works fine, if you tear it the right width you can't tell the difference.
Yeah you can just snip the first inch or so at the right width and then tear the rest - the layup appears to be horizontal so it tears nice and straight.
