I was trying to think of a good way to utilize space, and I had read somewhere on this site about being using some kind of fishing line or string to hang work from. My question is, is there someway I can get the string up without actually having to tack it to the wall? We aren't allowed to put holes in the walls, which is understandable since it's a new building, and I can't think of how to go about doing this. Any suggestions would be greatly appreciated. Also, what do you guys use to stick posters up when you can't use tacks? Sticky tak? Thanks in advance for all your help!
