If you want to recognize the miracles of 48 (HUH??) then wear a blue UN soldier cap.
If you want to recognize how the medine thumbed its nose at the miracles of 67, wear a dunce cap or clown hat.
Meanwhile, a black knit yarmulke makes NO statement and is easier to wash than velvet or leather. It also breathes better. I had a very big one once but it didn’t stay on even with clips which was too bad. I don’t know what I did with it; I think it was in an old luggage bag that I threw away.
