Sorceress Cagliastro has the best books and classes on Blood Sorcery.
Her old radio interviews are still up on youtube and they are invaluable.
It's better to use nosebleed blood for mixing with paint or ink, but it has less value for magical works, because you didn't deliberately make yourself bleed.
Actually deciding to bleed and doing it, gives your work much more "power."
Consider what the 4 cardinal directions symbolize too when doing blood sorcery.
The concept is that we and our blood are magnetic to a degree because it has iron. We have enough iron in our bodies to create a 3 inch nail...
To get started I would write petitions, anoint them with blood, and/or smear a drop on a sigil, then burn it.
It's really easy to draw blood. I use those exacto knife razors for art projects often sold at dollar stores, art supply, or office supply stores, and I just lightly rub on my skin like my upper arms, legs, abdomen, etc.
Obviously don't cut a vein. You just do it lightly.
Do not poke or cut your fingers which is always seen in witchy movies!
