What is a hypersigil? How do I make one?

[leemuria]

Okay so I think I know what a hypersigil is (kind of): something that you create, eg. a work of art or piece of writing, that is imbued with power relating to your intentions while making it? Like if you make something with positive intention and focus on your hopes for the future when crafting it, then that object can become kind of like a good luck talisman?
I'd love to know more and know how to turn my next craft into a hypersigil. I love knitting, would love to make something that I can wear that will protect me, or something that could bring good luck to whoever I make it for.
