I made a two-layer taiko obi from a summer obi. It's a light pink color. I don't know the material, but it's stiff. It's divided into the part that wraps around the waist and the taiko part. The waist part is 191cm long and is a free size. The taiko part is secured with Velcro, so it can be extended for storage, and there are no creases on the obi's crest. ○ Information on the Obi Pillow Base As shown in the last photo, the obi without fasteners tends to slip down, so using this will keep the obi from slipping and provide peace of mind. It is sold separately.
