Hey there everyone-
One thing that works for me is simple little pick strokes down and up on each set of strings
Start with the G then D then A then E, down and up on the same series of strings.
Then try down on G and up on D- three minutes
Down on G up on A- Three minutes
Down on G up on E- three minutes
Now back to just the G string.
Now mix the Rotation
down on D up on A, down on D up on E.
Same with A string.
A few minutes a day will help your picking holding hand, promise!
Have a great Turkey Day , Everyone!
