So we're making a movie theater room and it's set up and going well. The walls need some panels to break up the sound reflection, and rather than do curtains I wanted to do something geeky. I saw some bleach shirt techniques in reddit, but since I got felt for the texture and you can't bleach that, I used white fabric paint. I made 11 canvases, then cut black felt to fit, then traced out the logos on parchment paper, cut them out, ironed them onto the felt, then sprayed the relief pattern on. After painting, I had to wait 72 hours, then washed them, then mounted them to the canvas frames I built.
Take a look! Here's the room all together, see if you can guess the logos!
This is the blank canvas; I ran out of paint for the Matrix one before the first movie in the room.
