I am attempting to make a autograph book out of an 8X8 scrapbook. I cut cardstock into 8X8 and am planning to put background paper on the top to eventually glue a picture onto and have the Characters sign on the bottom. I have about 50 double sided pages to stick that background paper onto and eventually the photos on top of it. I need advice on what kind of adhesive to use. I'm thinking that spray adhesive is probably the fastest and most economical Any suggestions on brands or advice...maybe I shouldn't even be using this kind of adhesive.
