Fukuro Obi is a grade less formal than a maru obi and the most formal obi actually used today. It has been made by either folding cloth in two or sewing two pieces of cloth together. If two cloths are used, the cloth used for to make the backside of the obi may be cheaper and the front cloth may be for example brocade. Not counting marriage outfits, the fukuro obi has replaced the heavy maru obi as the obi used for ceremonial wear and celebration. A fukuro obi is often made so that the part that will not be visible when worn are of smooth, thinner and lighter silk. A fukuro obi is about 30centimetres (12in) wide and 360centimetres (12ft) to 450centimetres (15ft) long. When worn, a fukuro obi is almost impossible to tell from a maru obi. Fukuro obis are made in roughly three subtypes. The most formal and expensive of these is patterned brocade on both sides. The second type is two-thirds patterned, the so-called "60% fukuro obi", and it is somewhat cheaper and lighter than the first type. The third type has patterns only in the parts that will be prominent when the obi is worn in the common taiko musubi.
