Those cases are awesome, bass case or not! It totally looks much better when the stickers start to overrun the blank spaces. It's like a memorabilia collage or scrapbook. Plus, they always seem to make good conversation pieces:
"Oh, you've been there? Me too!"
or
"Oh, you know that band?"
Okay, I've done some thinking and I guess it's okay to put stickers on that are not necessarily relevant or bands that you even know or like, but when you do get a sticker you really like or support or think is cool, that's when you start to overlap the ones you don't really dig all that much... eh?
I'll take some pics tonight too...
