How do you tie a sash belt?

To tie a square knot, start by holding the left tie in your left hand and the right tie in your right. Cross the left over the right, then bring the left tie back up through the center. Pull the ends tight, then cross the right tie over the left. Bring the right tie under the left, then pull it through the loop you’ve created so it comes out on the left side. Pull the ends to carefully tighten the knot, but don’t tighten it so much that you lose the square in the middle. Tug the edges of the square to smooth it out, then arrange the ties so they fall neatly on either side.
