I made this In design/technology class last year but never got around to uploading it. It is double sided, depending on whether I want people to enter my room or not. The left picture shows the "do not enter" side, as my room has no chimney and the window is always locked.
It was fairly easy to make and you could make an even simpler one using paper or card instead of wood.
Tell me any other ideas for slogans you can think up in the comments section.
