Please excuse my higgorance. I know little to naught of heraldry. I appreciate there may be some ettiquette issues but what is the actual legality of drawing up arms on the back of an envelope with a box of crayons and without any formal process, displaying it on your t-shirt, car sticker, signet ring, tattoo on right cheek, whatever.

Not asking for legal advice here by the way. Just a general, legally you can do what you like or No you can be prosecuted type steer... I'm also aware it's probably not the done thing.

No intention of going down any roads either, just curious is all.

Cheers!
