Removable GlueDoes anyone know the name of the glue that is removable on paper. I received a magazine and there was an advertisement that was glued onto one of the pages. The ad was easily removed by pulling it off of the page, and when I rubbed the glue on the back, it simply rolls off. I have been trying to the longest to find out what kind of glue that is, as it would be helpful in some of my crafts. Have a wonderful Thanksgiving.
