If you had to stick a bunch of cd's to a wall, how would you go about doing that? (This is a speckled wall with paint)
NO dont use glue or tape. It will ruin the walls when you take them down.
You can get in a craft store this putty kind of stuff. They use it on ceilings to put up the glow in the dark stars and moon shapes. It comes right off if you decide to take the CD's off your wall and wont leave a mark.
Double sided foam tape.
