i have a question. i just bought a blank wooden sign at ac moore that i planned on painting and putting a few other things on. the only thing is, there's nothing on the back of the wood that i can use to hang it up (nothing like on the back of a picture frame, there are hooks you can hang it on a wall with). i was thinking maybe i could somehow drill a hole in the wood, and then put a nail into the holes and hammer that into my door. would that even work? is there anything i can buy separately that i might be able to attach to the back so i can hang it?

i hope this makes sense. thanks so much!
