Clover maskes a really nice thimble that is the only one I have ever been able to use comfortably. It has a "rubbery" part that fits over your finger, and a metal tip for pushing the needle. They are color coded for your size. A little more than the metal thimbles, but works great! I can now comfortably sew for hours, and my finger is not sore anymore. Love it!
