Maru obi , is the most formal obi. It is made from cloth about 68cm wide and is folded around a double lining and sewn together. Maru obis were at their most popular during the TaishÅ- and Meiji-periods. Their bulk and weight makes maru obis difficult to handle and nowadays they are worn mostly by geishas, maikos and others such. Another use for maru obi is as a part of a bride's outfit. A maru obi is about 30centimetres (12in) to 35centimetres (14in) wide and 360centimetres (12ft) to 450centimetres (15ft) long, fully patterned and often embroidered with metal-coated yarn and foilwork.
