Hi,
I use a leather thimble on both hands when quilting on a stationary frame. I learned long ago to quilt with both hands. I use a tan leather thimble on my right middle finger and a short black leather thimble on my left thumb. Before I became a quilter I never used a thimble. Now I need one just to sew on a button. Every time I find the kind I use in a quilt shop or other store I buy several. I have them all over the house and in all of my little quilting kits. THe brown ones have a little plastic disk in the tip that keeps the needle from peircing the leather and the black ones have a little metal disk. I can get about two bed size quilts out of a thimble. I have tried all differnt kinds over the years. It seems the more expensive they are the less I like using them. I was never able to use a metal one.
