So I'm thinking about fake-upholstering a wall in my bedroom in my apartment to create a focal wall without having to paint. I don't want to drill holes 'cause I'll be moving out of there in like 9 months, so I figure I'll just thumbtack the fabric to the wall, hiding the tacks.
Would hammering in the thumbtacks/pushpins into the wall gently help these thumbtacks stay in the wall better? If not, what will? I know that not moving or re-tacking the thumbtack will help it stay, but any other suggestions would be awesome.
