I would love that! I’ve searched for existing threads but haven’t found quite the right one. @roger_holland may know where one exists.
Stacy, I’d like to know more about what you mean by pointing the thumb toward the headstock enabling you to stretch farther. I definitely notice - especially on the thicker strings - that it’s much more difficult for me to fret across with my smallest finger unless I do that with my thumb. Having my thumb perpendicular to the neck (pointing “up”) makes my palm sort of “cup” a bit, which extends the reach needed for my shortest finger. I end up doing kind of the opposite of what Justin says he does.
So, yes, a thread on this, please. We can include photos, too.
