I'm new to trad archery and still working out the details on my form. I'm trying my middle finger in the corner of my mouth but can't get a consistent anchor. Any tips on finding a solid anchor?

Howdy there.... I too could never get comfortable with the finger in the mouth anchor.... I put my thumb knuckle right in the little dip under and behind the ear lobe and I let the cock feather touch the tip of my nose. That gives me a double anchor point.....

I use my second finger on myfirst molar.
