I'm wanting to start to practice Goetia in the near future, however a few things I'd like to ask.
1. Is it necessary to put the seals and other designs on calf skin, metal, and other similar materials, or would other materials, particularly wood and paper, work? Metal I could eventually progress to, but I doubt I am going to get calf skin any time soon.
2. What books are recommended for beginners? Any books that could help me start out would be greatly appreciated, as would be any online materials you can think of.
3. Any other advice, personal or general, that you can think of. I don't jump into things easily, and while I'm hoping to have things work well, caution is a good strength of mine, so it will be some time before I'll try this. Perhaps due to my age it makes it difficult to find time and space.
