This pattern allows for any size yarn as well as any size crochet hook. It is stitched from the toe to the cuff. This includes an example of a sock that measures 9.5 inches (24.1 cm) in length and 3.5 inches (8.9 cm) in width.
See a photo step-by-step of doing the double treble crochet stitch. Yarn over hook three times, then insert hook into next stitch. Yarn over hook and draw yarn through stitch - five loops on the hook. Loop yarn over hook and draw through two loops, (there are now four loops remaining on the hook)
