I use a glue runner (I like Scoth brand), glue dots for embelishments (I keep Craft and Minis on hand), and Mod Podge for anything that I can't use the others for. I also use a spray on sealer for some things that will be handled a lot to help preserve them a bit longer. HTH!
For Christmas I'm wishing for a Xyron Creative Station for adding adhesive, magnetic backings and laminating!
