This is not a tutorial. It’s actually more of a warning of what not to do. There are many graphics design tutorials involving Photoshop software. The basics are online. If you cannot afford Photoshop, there are free opensource software like Gimp and paint.net.
Now, that’s clear, the main issue is the paradigm of magick that you’re using. In other words, LHP or RHP? Black or White magick? Is it your own servitor? Is it your own egregore for a company logo?
Are you attempting to create a talisman in the Judeo-Christian-Islamic (JCI) tradition? The GoM/Damon Brand stuff falls into this category. (Note: I will use the terms paradigm, system, method, and philosophy to mean the same thing.)
These are important questions to consider. The infamous Seals/Pentacles of Solomon are designed to attract certain spirits and channel certain energies in the JCI realm. The same (more or less) with the seals of the Goetia. The Alphabets/fonts used in these seals are created to channel these energies and entities. Malachim, Passing the River, Angelic, Hebrew and Enochian are common examples of these fonts. This also applies to the languages of Latin, demonic enns, Enochian, Hebrew, and Arabic etc. So, one should do the research into these entities and the system that they are in.
My point is, do not mix different systems! Don’t try to use Hindu gods in a JCI system. No mixing LHP with RHP. I know that Chaos magick is the thing now. Even then, stay within that paradigm. For more details, read Jason Miller’s “The Sorcerers Secrets”.
Hoodoo mixes different entities under a JCI system. Voodoo uses the Loas/Luas under a mostly Catholic paradigm. French, Latin and African languages are used.
I know that there are books where both Angels and Demons are used in the same seal. The GoM Henry Archer and Damon Brand books. Consider that these entities are both in the JCI system. That’s why it works.
Most sigils are generated using several different methods. All of these are covered in several posts on this forum. For the JCI paradigm I recommend using the (Kameas) Number Squares method and the Rose Cross Method which is based on the 22 letter Hebrew alphabet.
If you don’t like Hebrew, Enochian, Angelic and Malachim etc. can be used.
Most sigils are surrounded with a Triangle, Pentagon, square or usually a circle. The seals in Simon’s Necronomicon are a good example of this. I’ve even seen an octagon used in one book! It depends on your preference and what the design is intended for. When using the sigil in a six-pointed star (Star of David) or a pentagram, know exactly why you are using it. These are powerful symbols for a reason.
These symbols are connected to systems, entities and energies that have existed for thousands of years across countless cultures.
When creating your own servitors and egregores, I recommend using other sigil creation methods.
Use whatever fonts you feel comfortable with. I prefer either the Theban, Egyptian, Runes and Enochian fonts myself.
Again, do the necessary research and know what you actually want the talisman to do.
Once your design is finally done, of course, you have to charge it. This is also called activating it. Again, there are several sources about this on this forum. Just putting in the thought, study and research while creating your design will start to give it the energy it needs. You stare it with intent until you go into the Theta-Gamma Sync (TGS) state, also called gnosis in other places. More info is easily found on the BALG forum.
The talisman if kept on paper, can be easily destroyed. Make them into tattoos, rings and medals. They can be custom made by artists like Talimancer. T-Shirts and blankets can be printed with them now.
This is all for now. Thanks for reading.
