I was wondering if there is a stander way of making sigils or if I can create my own. If I do is the intent enough to charge them?
You can make it however you feel like it.
The many ways that you can create and use a sigil is up to the magician and your experience and experimentation to focus on your goals and ritual.
The letter elimination method is the simplest way to make a sigil. The more specific the intent the better. Mastering the art of how to make a sigil properly comes with experience. I like working with paper and a pencil that way you can easily make corrections or changes, however you can experiment with other methods. Digital art, paints, collage, ink pens, can all make excellent sigil mediums.
Scribble, scrabble…so long as u channel the emotions u wanna put into the spell…random as possible…works fast
