A palm thimble is a useful tool when doing sashiko stitching. The pad of the thimble, which is positioned over your palm, helps push the long sashiko needle through the fabric and makes stitching easier.

This lightweight metal thimble fits comfortably over your finger like a ring. It is adjustable so it will fit most. The pad of the thimble has little dimples that the end of the needle can rest in to keep it from slipping as you push the needle through the fabric.
