I do a little hybrid and I use the following:
Glue Stick just a 3M for attaching most things. I *heart* my glue stick. I use Zot Dots glue dots or foam dots for things like buttons and fabric flowers that the glue stick won't work on. And for my big projects like my mailboxes I did, I used spray adhesive. I love that for when I glue paper to like a metal box or something else. I used to use a tape runner but it was so frustrating! I am a glue stick girl!
