Boo sign craft

This is a Halloween craft that I did for myself. I used Mod Podge for the first time ever! I admit that I was a little scared at first because I didn't know what to expect, but now that I've done it, I'm hooked. If was so easy and I loved the result.

I made this Boo sign because it seemed really simple and I already had some of the supplies. I found the idea here. This is as far as I have gotten because I'm a little stuck.


The letters are just sitting on the plaques right now because I don't know how to attach them together. The blog doesn't say exactly how to do it. I'm guessing some sort of glue, but what kind? Wood glue, tacky glue? I also don't know what to put it on to hang it up. Does anyone have any ideas?
