Some quilting gurus recommend putting thimbles on all the fingers until you are accustomed to the feel of the one on your main quilting finger. I had one made by a friend who makes and sells thimbles professionally. It is silver and has my birthstone on it; It doesn't go out of the house, but I really make use of it. I also use the dimpled variety with a bandaid inside to make it fit. For the underneath finger, I wrap it in the strong tape vets use to keep pets from chewing on their wounds. Hospitals now use it for wrapping puncture sites.
