I find that

Drawing sigil from the Goetia by hand, not by putting a paper over the sigil, but by looking at it and drawing it helps me out a lot in magickal works. Even if the drawing is not so good I feel as if I have drawn(no pun) the spirit near me. Anyone else have this feeling ?

As an experiment a few weeks ago, I did the same thing as what you did above, and compared it to the same sigil, but simply printed out. I noticed the difference as well. Hand drawn ones have more power and are easier to open, since your putting more of your own energy into creating it too.
