You may seem like an odd analogy, but finding and getting fitted for a thimble that works for you is JUST like the process of finding a bra that fits. Almost no one is fortunate to be able to go into a store, pick one off the rack and have it fit the first time. (And if they are, they're keeping as quiet as the women who had no symptoms when menopause hit.) I have several types of thimbles, which I use for different things; and after many years of frustration buying bras, I am now making my own.... and am very happy!
