I was the flower girl in a lot of weddings growing up, and I have a collection of personalized napkins from most of these nuptials.
As I've "grown up" I've noticed that couples don't have these napkins at their weddings anymore. But paper-source is bringing back custom printed paper goods with custom coasters, placemats and napkins. And they're typographically much more fun these days!
I love the idea of wedding coasters, because I know how ofter people save and collect coasters. I feel like these are mementos that could end up sticking around for awhile!
