I use a thimble on my middle finger as I haven't found one I truly like for my thumb. Before using thimbles wear them on your finger for several days so you get used to them. I use a feather weight thimble it is harder to find but less than $10.00. They are ring sized and have a heavy flat top with a ridge. I love mine and use it all the time. I also collect thimbles and small sewing kits. I found one the other day at my LTS it is an advertising one form the 1st National Bank of Arizona and has a piece of felt for the needles and pins then a braid of 16 different colored threads to sew with and a pair of scissors! In a very neat folder the size of a pocket comb. I just love my little treasures.
