I wear a black leather thimble on my left thumb. Long ago I taught myself to handquilt from both directions with both hands. The hardest part is getting it to stay on when that hand is under the quilt. When quilting left handed I use the thumb with the thimble to push the needle. They carry them in most LQS and even Joanns. It is shorter than the light brown leather thimbles I use on my right middle finger.
