Insider took the class and shared some of it with us. I didn't realize how much I didn't know! Turns out I've been using a cloth napkin totally wrong! Apparently you're supposed to fold the napkin in half with the crease towards you and the opening out, and then you bring the napkin to your mouth and open the corner to dab it with the inside so that all stains are hidden inside the napkin. I always just threw it on my lap and wiped my face as needed. Oh, I've also been holding stemmed glasses and drinking out of them incorrectly because you're only supposed to hold them by the stem, and not throw your head back to finish ever last drop of wine. Whoops! Who would've known? Check out the video to see what I mean and the rest of the items!
