A thimble is one of those things that you don't think about until one day, after continued struggle pushing a needle through heavy fabric, and several stabs to the fingertips of your other hand, a lightbulb goes off above your head and you think, "Ah, a thimble."
Small, functional, somehow cheerful, I can see why people collect them. There is even a museum dedicated to thimbles. The Fingerhut Museum. I went through a few thimbles before I found one I liked. There was an aluminum one that felt flimsy and hard at the same time. And a brass one that was a size too large so I wrapped a Band-Aid inside to keep it snug on my finger. When I pulled this one from a basket of different sized thimbles and put it on my finger it felt just right.
