One of the easiest knots to learn. Try this:
- Fold each end of the lace into a single "bunny ear." You can hold the "ears" in place between your thumb and pointer finger on each hand.
- Cross the bunny ears so that they form an "X" in the air.
- Loop the bottom bunny ear over and through the top bunny ear. This will create a second knot.
- Pull the bunny ears out to the side away from the shoe. This will create a square knot that will not easily come undone and will hold the shoe in place.
