I have never learned. I start out with a thimble and eventually have to take it off. I can't find one to fit. They all fall off. I have fairly small fingers and none fit. I think I'm just spoiled and don't want to wear one. I do try, because the needle seems to find the same spot right next to the nail on the middle finger of my right hand. I can't even see the hole, but I sure can feel it!!! I keep trying but I'm beginning to think it's a loosing battle!!!
