Northeast handkerchiefs in the middle of the two corners of the part called what

The part between the two corners of a Tohoku handkerchief is called the "centerpiece".

The middle piece is the thin strip between the two corners of the Northeastern handkerchief, usually narrower, and made of the same color and material as the handkerchief itself. It is mainly used to decorate and fix the hand set. During the hand set making process, the center trim piece needs to be woven together with the two corners of the hand set to ensure that the whole hand set is firm and beautiful.

Besides its role in the making of the hand set, the center piece has some practical value. The center piece can be used to tie around the wrist to prevent the hand set from falling when in use. In addition, the centerpiece can be used for everyday purposes such as wiping sweat or glasses.

If you have further questions about the material, making, or use of a hand set, consider reading a book on the subject or consulting a craftsman. You should also be careful to choose a good quality and well-made hand set when buying one to ensure safe and comfortable use.
