I stuck up my unfinished posters in a subway near my house to see what they would look like. I think they look pretty good an when they are finished I am going to paste them up using wheat paste. This is a very sticky mixture made from flour and water. You make it by mixing 4 cups of water for every cup of flour. You then smear it on the surface you will be sticking a poster on with a paint brush and then stick it on. You then put more wheat paste over the top to water proof it slightly.
