I recommend buying more than you need for this item. There is never enough koshihimo when it comes to kimono. I recommend buying a set for dressing and buying a set for bringing with you while you go out in a kimono, as they are excellent in holding up your sleeves or keeping the hem of your kimono out of the way. I find it cheaper to buy these than to make them myself. The material also holds very well even with a single knot. However, the koshihimo does need to be ironed after each use.
