Hi Jacqui. I decided to give the thumb rest a try. I think it will be a good aid for me to consistently get my right hand positioned so that I can get the holes covered. I’m thinking that the muscle memory will develop to where I can remove it later if I need/want to. The cost was $4 + $5 shipping
Thanks, Linden. I went to the url you cited and read the comments. They are mostly negative as to thumb rests. For now I’m going to see if the rest helps me to keep my right thumb consistently in the appropriate position. It that doesn’t work, I’m out $9 so it’s no biggee.
