I took some ideas from others and made a few signs, some one asked for a sign they could put on there door to help parents and people from walking in and out and causing a disruption in Primary, so here are some
"Reverence in training, sharing time in progress. Please help keep the reverence."
This one looks like a road sign and say's
We're Trying To Be like Jesus, and follow in his way, our reverence is important, to show our love today So please help us keep the reverence, and follow in His way, by keeping this door closed, on this very sacred day
