How should I hang posters behind this roll down screen?
I have this roll down screen for my projector, and there's a huge empty space behind it. I'd like to hang some posters behind it, but I don't want to just use tape. I think framed posters look better, but they're too thick for this setup.
The posters can only stick out about 1 cm from the wall, otherwise the curved bottom of the screen won't be able to slide over them.
Any tips on how I could hang them?
