I'd like to know what "glue" would work best to adhere paper to wood? Is there a difference between using artist's gel mediums or decoupage? What is the difference between Mod Podge and Royal Coat Decoupage? Also, what would be the best way to seal and protect this when I'm done...varnish, poly urethane...? Thank you very much.
A gel medium would work but it's overkill in my opinion. There are differences between all the glues and it's mainly proprietary formulations. The gel mediums are used as collage glues but they aren't specifically formulated for it. The decoupage glues are formulated for just this type of work. I would venture to say that's the main difference between the Mod Podge and the Royal Coat - formulas. They would probably both work fine. I would use one of the decoupage products. You can use a clear acrylic sealer as a finish. If you use Mod Podge I'd use either the matte, gloss, or satin.
Best of luck with your project!
