I was eating and now I'm back.
As for sigils, once you've created one, keep it on you for a while or focus energy and such on it to charge it, but after that, forget about it. I don't mean this figuratively, but literally. Forget what it looks like, forget what it's for, and it'll work its magic.
Then again, there are different ways to go about sigils and all that jazz.
In their simplest, sigils are just intent in picture format.
Do with them what you will.
