I use commnd strips for my dorm room. I use them for everything, and I absolutely love them. I tried using putty at first,but after a while they dry up, and my things fall off the wall. It was horrible especially when they fall during the night, or make a mess. I love using the strips to hang posters, pictures, and bulletin boards! Command strips make my room look neat, and awesome, and I will never ever use anything else. The strips last until you decide to take them off, and when you do, they come off cleanly...as if nothing was there! Command strips are awesome, and I will never stop using them at all.
