In the SCA? Very.
[EDIT: Herald buddy says – “there ARE corollaries to the rules so we need to judge items on a case by case basis to take all of them into account.”]I can certainly look at your idea and give you some advice. I can also reach out to the SCA Heraldry Chat Facebook group and get thoughts/input from them.
Let me know what you’d like to do. I’m happy to lend a hand.
