Please Knock - Buzz if Need Bee Door Hanger

Anyone can say "do not disturb” or “please knock,” but why not have more fun with it? This friendly bee says, "Buzz if need bee" to tell people you're busy but it's okay to interrupt if necessary. I use this one when watching a video lesson that has a pause button, for example. Like a traffic light, the yellow border is designed to coordinate with the red (deep work in progress, do not disturb) and green (hop on in) signs in the same collection!
