Step 8. The toothpick is used to loosen the loops and make distance between the button and the fabric. This is necessay. The button would be too tight to function properly otherwise.

Step 9 is to remove the toothpick and sew upwards under the button, but not through the button.

Steps 10-12. Since the sewing isn’t tightened down, you’ll need to secure it by wrapping the string around it a couple of times. (This is why you don’t see through the button in step 9).

Steps 13-rest. Sew through the existing loops and tie a knot to secure the thread.
