Well done! You've got the hang of it.
Here's a challenge. Make four knots, but rotate the blank one side for each knot spacing. For example, number each side from 1 to 4. Have 1 face up, cut and fill in the first kerf. Then have 2 face up, advance the kerf to the second knot position in the series, cut and fill in the second kerf. Then have 3 face up, advance the kerf to the third knot position in the series, cut and fill in the third kerf. Then have 4 face up, advance the kerf to the fourth knot position in the series, cut and fill in the fourth kerf.
Next, go back to knot position 1, cut the kerf in the opposite of face 1, and fill. Proceed through the rest of the knots in the same manner, always adjusting the knot position to the corresponding face.
You'll end up with a fantastically intricate knot, without the noticeable parallelism. Thin knot material will look best for that technique.
Keep experimenting.
