Thank you for all the tips.
Cindy, I had never heard of the paper clip method for bracelets, but will keep it for reference in the future. (It doesn't work for necklaces as far as I can figure out.)
Jessica, the magnetic claps look helpful. Will investigate those further.
I have been practising this since originally posting. The do it in the front bra method, I can't get to work. Lack of coordination and difficulty focusing my eyes well enough a right distance, makes it quite tricky.
After much experimentation, with the behind the neck approach I decided the thumb and forefinger nails of my left hand (growing all my nails) are basically getting in the way too much and don't let me have enough sense of where everything is.
Okay, don't know if I just did something a bit rash, but I have trimmed those two nails only, and now my success rate has gone up dramatically.
Is having a short nail on the thumb and forefinger a good solution? Have I been too impatient?
I am not sure, but right now, I feel satisfied.
