What can I use to stick my posters up on my wall? Blu-tak won't work as they are printed onto silk material stuff. I've got some sticky-fixer things, but they leave behind a horrible mess when removed, both on the wall and on the poster. Removing it from the wall is probably easy with some alcohol and a bit of rubbing, but I doubt that'd do the poster any good. So, anyone know of anything good, that doesn't leave a mess. I know frames are the best solution, but I can't afford them, and I couldn't find any in 36x13" size.
