I couldn't use one before I started quilting. Now it is out of self-defense, and aching fingers that I started wearing one. I found that most of them were simply too big and kept falling off. When I got one small enough so that it didn't just fall off, then I could wear one.
My fingers are very average sized. I'm not sure why they make the thimbles around here so big. I have about three that I can use and am afraid of losing them. One has been kind of shaped into an oblong shape. That makes it stay on better.
