Every time you tear off a piece of tape from the roll, you're left with the perpetual conundrum of peeling it off the next time. Instead, fold the tape to the side and tear it to leave a tab for easy access later.
This tip comes from filmmaking tips site The Black and Blue. When you have to mark locations for actors all day, you don't want to have to fiddle with tape constantly. The technique, as shown in the video above, makes it quick and easy to tear off multiple pieces of tape in a row and it always leaves a tab for you to grab onto the next time you need a piece. While you do lose a very tiny bit of tape in the process each time, you can weigh that against the time (and likely extra tape) you save by not having to fiddle with picking at the end of the roll with your fingernails.
