Body weight hanging.
I like to study on my bed more than at my desk.
I am thinking about putting a big hook in a stud in the ceiling above my bed. I am thinking I will hang a rope from it so that I can attach my bib to it. I could then adjust the tension by adjusting the strap on the Bib. I figure I could hit every possible angle this way. I could lay on my back, on my sides. I could sit forward for an over the shoulder and I could lay on my stomach for a btc.
Hopefully, after a few months, I would have to trim the rope some.
