I have been able to place the custom painted flags on my masts (and hull where I sometimes follow maritime flag protocol), and while I often paint a national ensign, or personal signal, I would like to suggest either craftable and/or cosmetic pennants to fly atop our masts? Maybe akin to a longer commissioning pennant, or maybe a swallowtail or triangular pennant?
