For this type of thing, I prefer using paste rather than glue. Elmer's no longer makes their school paste (the white stuff in a jar that smelled like peppermint!), but there are substitutes on Amazon that look pretty good. What I like about paste is that it is easy to control the amount as I apply it. I use a fingertip and keep a damp washcloth nearby to wipe off occasionally. If I ever run out of my supply of Elmer's, I will probably try this one:

This would be another one that would probably work:
