The trick is to take your time with them. I’ve been having to draw a Goetic sigil every day for the last few months, as part of my Goetic operation I’ve been doing. as long as you get relatively close, they don’t care. It’s the intent that counts.
Here’s the post where I called up Bael for my operation, the first evocation in it. You can scroll through and see the sigils of all of them if you want.
