I've got 3 unused felt picks to give to anyone who'd like them. They're 3mm, with an elliptical cutout for "extra grip and flexibility." Holler, and I'll put them in an envelope and mail 'em.
I’ll DM you. I’d like to try one for reference; but I’ll give the other 2 to students in the fall. We had some leather picks made and also some synthethic felt, for the students that complained about their strumming fingers hurting.
