The herringbone stitch is the pale purple thread together with single fly stitches in yellow and red.
The row across is another form of herringbone stitch - twisted lattice band. This is made up of double herringbone stitch which has been laced. I used four colours here, pale purple, yellow threaded with orange and red, although normally just two colours are used. [I should have taken a close up] This stitch is number 121 of Take a Stitch Tuesday. The fabrics are remnants of vintage wool and cord. This is a picture of my mother wearing a coat made from the purple and black fabric. I'm not sure of the date of the photo but she is 86 now and I can remember her wearing the coat when I was young.
