I don't know that I would embroider a patch on one of my kilts. It's too permanent and I tend to like to change the kilt pin on occasion as my tastes change. However, I do wear an antique (1890) hallmarked silver Mackay Clan Crest as a kilt pin most of the time. It is quite a bit heavier, wider and slightly larger than a traditional modern white metal crest so it serves it purpose, and that is to keep the kilt apron flat. Works great as a kilt pin and is unusual enough to not look out of place.
