TAST 28 - BRETON STITCH
Breton Stitch is derived from Herringbone stitch. So, its pretty easy and such a straight forward stitch. This follows a curve well and can be used as a decorative edging stitch or a filling stitch.
BEYOND TAST 28 - Diamond Stitch
As the name suggests, this stitch creates a diamond pattern. But its a complex stitch involving a sequence of steps. It was difficult for me in the beginning, then I referred Mary Corbet's video in youtube videos and got the hang of it. The struggle is worth to see the end result of the diamond stitch though.
