Obijime is a string about 150 centimetres (4.9 ft) long that is tied around the obi and through the knot, and which doubles as decoration. It can be a woven string, or be constructed as a narrow sewn tube of fabric. There are both flat and round obijimes. They often have tassels at both ends and they are made from silk, satin, brocade or viscose. A cord-like or a padded tube obijime is considered more festive and ceremonial than a flat one.
