Questions about runes, servitor's and sigils

I’m thinking about doing something similar to what the wolf of antimony occultism did with his Ravens of Antimony. instead of using a sigil im planning on using runes or creating a rune sigil then binding it to the servitor. Im am completely new to runes and have yet to purchase any books but i know they are basically sigils. Has anyone done something like this before and im wondering are runes are they less effective if drawn and used on paper.
