I used to have a bottle opener on one too! That's awesome! Where did you put it? Mine was a salvage opener from the 40's and I ended up putting it on the upper bout and then having to use a gig bag because I couldn't latch the case! *doh!*
I think you should make them your own...if it's your own just the way it came, then that's great (you've got the feeling we're seeking by muckin' ours up!), but I can never leave well enough alone.
I've got one that's pretty covered in stickers - and it all started because someone smacked an "Indy CD & Vinyl" (the record shop sponsoring the show) sticker on it while we were playing. I knew I'd take it off once I got home (haha!) but then it I didn't and it kind of grew on me. Now it's got one of our bands stickers, a Katy K sticker and some other various stuff slapped on it.
Do what you want and have fun with it!
