1. With your left hand open and the palm facing you,
2. Lay the yarn in your palm (with the tail end hanging past your little finger) and wrap the yarn over the top of your index, middle, and ring fingers,
3. Then bring the yarn back under the fingers, crossing the yarn as it meets the start at the top of your index finger, and to the back of the ring you just made.
4. Use your thumb to hold the crossed yarn in place, and insert the crochet hook under the first loop, picking up the yarn from the back to the front, then make one chain - this chain does not count as a stitch it is there to secure the loop onto the hook.
