Clover adjustable palm thimble
Palm thimbles are used for traditional sashiko stitching. The eye of a long sashiko needle rests in the base of the textured thimble as fabric is gathered on the needle. Push through with the palm and continue stitching. I find this to be a very efficient technique and super helpful when working on large pieces of fabric, like a quilt. The fabric holds the needle in place as your hand with the thimble guides the needle through the fabric.
For me, it's awkward when working on smaller pieces of fabric. Definitely a fun technique to try!
