It is not a question of which side of the leaf you use and the other you don't. It's just which side you lay on the board. Split the center stem out, you have two halves. The left half you wrap one direction, the right half of the leaf you wrap the other ... but in both instances you put the veins of that half upward on the board in front of you so that the smoother leaf surface winds up outside and the veins in. Makes a big diff in appearance. It's just as easy to wrap left to right as right to left.
I am in Newark DE, I thought you were in Northeast MD, more like 10 miles from you. Got you cornfused with someone else I suppose. I bought a motorcycle in Meriden once. Took the train to fetch it. My buddy scored one near Danbury this last Winter. I toted the trailer up for him to fetch it. Train was better. It's an ugly ride from here to there.
