Parallel Bow Knot
This is a common knot in bowties around the late nineteenth century. It has tied Basic-bow-knot while keeping the width so as not to make wrinkles at the center of the knot. It is a way of knotting to make the upper and lower horizontal lines almost parallel when finished.
It is thought that there was a tendency to become a parallel shape with nature because it was tied at the time with a straight bowtie. It looks the same as the Ichimonji-musubi-knot of the Japanese kimono, Hakama.
