I saw this on YouTube bit over an hour ago – heraldry Obtaining Your Coat of Arms – Fact and Fiction: https://www.youtube.com/watch?v=XXOR6mkoxiI (about 9:35 minutes long).
I was aware of the information in this video for a few decades before I purchased a Coat of Arms from a local renaissance faire seller about a decade ago. I went into the sale knowing the warnings that were mentioned in this video. It wasn’t that expensive. One day I will design, or have someone design a Coat of Arms / logo for my business. I know what I want it to look like, but don’t have the skills to design it myself.
