Needed: Glue

I need a crafty recommendation. I am gluing glass domes on top of paper artwork inside pendant trays. I now realize I should have glued the paper TO the dome, and then put those inside the pendant trays. I will do that next time. As it is, I have to resort to putting Diamond Glaze on top of the artwork, and pressing the dome on top, keeping it pressed down with a book. I plan on cleaning up the goop that gushes out, afterward. 

Any other thoughts, besides, "Dang, she's an idiot?"
