well, I'd thought that maybe a darker background might be a good idea for the etched glasses and had considered possibly even painting the inside of it black, but the more I thought about the more I realized that it would make it look a lot like particle board "kit" furniture. so I will probably use a stain, instead.
I think what I will probably do first is go through all of my glasses and see how many of them actually are etched. I really don't think that there are that many, so it might not even be worth worrying about them, as much as the screen printed ones. there's really no reason not to make two cases, either. So I could do a big one for the printed glasses and a smaller one for the etched ones, if there are enough to warrant it.
either way, I might do a couple sample pieces, then hold a glass in front of them and see what works best.
Thanks for the input!
