I got an email from Wedding Paper Divas with a 40% off coupon code for personalized cocktail napkins and coasters. This wasn't something I was even considering, but after looking at them they're so stinkin' cute! Obviously this isn't something we need for our reception, but I'm curious how much it would cost to have the cocktail napkins. Is there a rule of thumb for how many per guest? I'm having about 80 people. Oh, and do they get served with the cake?
