To start with I tried the leather thimble and too quickly the needle started to go thru it. Then I tried the plastic one that you boil and adjust it to the finger, it worked well and I bought a couple. Then I went to the Road to California Quilt show and found this lady that makes silver thimbles. She measured my finger and sold me a thimble that fit my finger. It is wonderful. I have three because I bought one a year, haven't seen her the past couple years so hope they have a booth this year. They are not cheap, but each one I have is special, one with an angel, one with a heart and one with a fairy.
So why so many? One in a sewing basket, one on my thread stand and the other one in my portable sewing kit. It is very hard to sew without one now and it is like needing 2 pairs of glasses, if you only have one pair that's when they break before you need to return to the optometrist.
