I got a little behind on my TAST stitching, so here are three weeks worth at once!
Week 4 was the Cretan stitch, shown on the left. It's very similar to the feather stitch of week 3. Week 5 was the herringbone stitch, which I really loved. I can see this being a great border stitch. Week 6 was the chevron stitch, which was also fun to stitch.
