Renting napkins.....

For those who have rented napkins other than what the RH provides for you, what did you rent them for? Or, what is the going rate for renting per napkin?
My mom actually decided that she doesnt want just plain white napkins, but sage ones, so Im just trying to get an idea of what the cost is for her. TIA!!

ooops....I meant to post this on '07. lol But if you guys have looked into this, I'd love to hear what you found out.
