Here's the dual strap solution I rigged up:
This came out of several threads here back in the wintertime, and some experimentation on my part until I got just what I was looking for - something comfortable that holds the uke securely without need for any support by my arms, wrists, and hands, and exactly where I want it for optimal playing.
I've been very happy with it.
I did some months ago end up replacing the two thin straps with a guitar strap and a luggage strap, so I'm due for a new video ... which I was planning to make anyway, so I'll update here when I do.
Possibly today!
Forgive the double entendre title. Other body parts getting in the way was one of the challenges I was looking to solve ... and the title garnered some amusing responses, and just the right amount of attention to my (actually serious) query. It was fun, and helped me get answers that worked for me, and have (according to comments I've received) helped others as well.
