@agaric I'd look at YouTube there are several witches and other who are practitioners in the occult who do stuff on sigils, but really sigils are very much up to the creator of the sigilsince they work through symbolism so you can pick and chose your preferred sigil creation method.
@agaric the guy who popularised their use was austin osman spare, in the early 1900s! he wrote a lot about them in his books, which are all public domain iirc. unbelievably floral victorian writing tho. i think if you google his name + sigils there's some easier to read guides too!
other ppl do sigils differently to him, but his stuff was the first(ish) and works well for me
