We all get oil that comes to the surface of our skin from time to time, as well as sweat. It can be sort of embarrassing. What do you use to blot your face?
You can pay $10 for a package of oil blotting pads/cloths from the store, or you can gather some of the brown napkins from your fast food restaurants, or coffee shop. The composition of these napkins make them absorbent and perfect for blotting.
Don't feel bad for grabbing a few extras. With the amount you likely get charged for food and coffee, the restaurant or coffee shop can afford to provide their customers with a few of these gems.
