Did you also learn to work rows of Four-Sided stitches like me – from the front of the fabric and from right to left?
Working hundreds of hems using Four-Sided stitches, I discovered a much easier and faster way of stitching. It is worked from the back of the fabric and from left to right.
Working this way is going to be the least stressful on your wrist joint, because in two of the needed three stitches it is held straight,
and for only one stitch it is bent.
Did you test it already?
