Begin by tying your 'starting knot' by placing the left lace over the other and pulling it under through the gap. Pull tightly.
Pick up each lace using your pinky fingers and get your thumb and forefingers ready like this.
Pinch your thumb and forefinger together and go under the lace. Your thumb should stay close to the starting knot.
Do the same on the other side, but go under the lace on the opposite side, like this.
Bring your left thumb and forefinger towards the opposite lace and vice versa. Pinch the opposite laces at the same time and pull through.
Finish by pulling hard to tighten the lace and prevent it from loosening.
