Just a little twist on a single crochet and what a fantastic affect! You grab the yarn with your hook instead of yarning over. I'm using a 2.5mm hook with 3mm Bobbiny Cotton Cords in this video. I wanted to keep the stitches tight.
For this basket I used 100m of the thicker 5mm Bobbiny Cotton Cord in Silver
And here's a closeup. I love that criss cross affect.
