Regarding the rites to construct talismans

I have recently received 4 talismans of which I plan to consecrate after the move. (Details on it later.) I have two books that offers rituals to do this and awaiting a third. I wanted to ask the following questions.

  1. What book/method did you employ?
  2. If I use one method in one book, will there be any issues if I later on use another?
  3. Is the consecration of a talisman a one time thing?
  4. Is there any preparatory work you would recommend?
    This regarding the pentacles of Solomon.
