i use a nice flexible plastic spatula to spread the glue and use heavy pipe clamps to apply the clamping pressure. that means you can't change it or cancel it once it is signed. it is not always the content that matters, but how it is framed to manipulate the meaning of that particular thing. sometimes you just have to touch a product to know it will work. great for decorating at home, events, weddings, and anywhere you can leave your mark. but it is fun to see them "boil" out of cover!
