Why do you want glue? Mod Podge, of course.
50/50 mix of glue and water
Fill a jar half way up with white glue (like Elmers)
Fill jar with equal amount of water.
Same as matte plus 1 TBS of clear varnish.
All of that said, I have read that the homemade Mod Podge is not quite up to par with the real thing. See this post. But, I don't care enough right now to not make my own.
