Actual question: how do you cut out bulletin board letters efficiently and neatly

I am a first year teacher and I am in awe of my colleagues classrooms. My small classroom is snuggled between two fourth grade classrooms and those two teachers have it really going on. My biggest question after spying through my door all day is, HOW THE F DO THEY HAVE THE NEATEST LETTERING ON THEIR BULLETIN BOARDS. And no, they aren’t using pre cut letters..
