I find that with mine I just gently scoop them from the side... for my flighty ones, I just sorta come at them a few times, they tend to dart away, as they are darting away they get those "ripples" on the side... I just scoop them up at one of those points.
Be very calm and make deliberate movements (but stay attentive).
They are VERY receptive to movement, so if you are pulling in and out and away, they are going to be hyper attentive to those movements. I really avoid jerky movements with them. Which can be hard if you are anticipating being bit... if she turns her head and you pull back, she is going to be watching your hands (just think of how they track fingers on the side of tubs).
My young male is a really flighty. I just calm myself before I handle him and know how I am going to come at him, and what my plan is to pick him up before I even open his enclosure.
I let them try and get away... just hand over hand and let them travel.
Baby corns are very busy snakes, adults are too. Very different from your BP.
Just be gentle and let her bolt, but let her bolt into your hand and try to anticipate her next move. She isn't going to leave your body so you do not need to worry, she will be more apt to try and run up your sleeve.
Hope that helps.

PS: I have never had a corn bite me in a handling session, although I know that a few have wanted to as I was coming in to pick them up. I think the deliberate movement is key, as well as scooping from behind the head AS she is travelling away from you.
