would you be able to instruct me on crafting a sigil of an archangel, the circle seals seen in the grimoire of armadel?

I do not work with angels, and would not feel knowledgeable enough to lead someone in such an endeavor. Sorry. When it comes to grimoires, I can recommend the works of  Jake Stratton-Kent, but again, he focuses on the lower beings.

I can give general advice on how to see spirits.
