I can’t find my measurements for the canopy sign (swear I jotted them into my phone but the evidence is otherwise…).
But this is a quick sketch of what I was thinking. Each side two laser cut-out pieces of ply, with the white ‘M’ cut of the top one, that painted white, and then the whole thing painted red. Repeat for the other side, screw on two hinges at the top and a chain lower down, and it’s done.
So the two pieces shown would be sandwiched together.
Obviously it could be more complicated, but I thought that was a nice achievable project for someone who wanted to do something for the space.
