Loop Knot

① Tie the scarf and bring the knot to the center as shown below.

② Wrap the knot you made in ① so that it comes to the front. The idea is to bring the knot and both ends to the front.

③ Tuck the left and right ends that you brought before into the knot that you brought before. Finally, adjust the left and right ends that you tucked in and the part that you wrapped in ② and you're done!
