I was thinking of ordering one of those Dremel engravers so I could make pretty Goetic seals, but would you say that it's as much making by hand than say, engraving them with a nail with bleeding hands? What kinda methods do you guys use? Unfortunately I've no way of casting anything yet...

The engraver's cheap though so I think I'll just order it anyway and try and see how it goes.
