I'll definitely have a problem with showing people - that is, if they want to put it on. I have the tiniest fingers ever; I think my ring is like, a size 4 or 4.5? But it's the perfect size.
I always have jewelry to symbolize stuff. I've had quite a few bracelets for SI - mainly orange and white ones

and right before I got my class ring, I got a "new perspective on life" ring from a fair vendor that I've gotten jewelry from before.
And I want to get a SI tattoo someday as well! I have it planned out, but it's changed before, so we'll see what happens.
Oh, and isn't Josten's seriously adaptable when it comes to resizing and changing rings? That's what we were told by our local rep. when he came to talk to us about rings.
