When eating out at fast food restaurants, we are usually given too many napkins that end up in the trash. Now we fold them up and take them with us. They end up in the car for kid clean up, in the purse for emergencies, on the vanity for makeup removal, in the kitchen as a substitute for paper towels or on the table as - surprise - napkins. I'm sure you can come up with lots of places to use these leftover napkins. We never let them go to waste.
