Are you having them made in bulk, or are you making them yourselves? Just wondering if they will all the say the same thing or if you can personalize them.
Normally I would say avoid your names and date on the favor, but I know H and I have a ton of Koozies and we love remembering what they are from. So I wouldn't hate if your name and date were on it. Or just the date. I like "To have, to hold, to keep your drink cold." Or something along those lines.
