I love to paint hands. Love them. All the joints and angles and fat parts and skinny parts and knobby parts… are your palms sweating just thinking about it? I, too, used to cringe when I got to hands- all the joints and angles make them a bit of a challenge. Make the fat parts too fat and you get sausage fingers. Too skinny and you get E.T.
