This may sound stupid, but I need to know what the best way/product to glue paper together is. One piece is regular paper, but the other piece is a little slick (a notebook cover.) It is crucial that these papers stay glued together. I'm customizing a notebook for my best friend, but I've never done anything like this before. It is a graduation present, and I'd hate for the front of the cover to fall off. Any help would be much appreciated!
