This started out just as a long strip, about 14" wide of sampler of ideas, sewing, cutting, on the diagonal, and thinking about reversibility. I've cut strips on the bias of linen, cotton and rayon fabrics. There is also, now some couching and free form embroidery going on here.
This is definitely not an obi, just roughly the size of one, 14" wide by about 6' long, but I have quite a few of them around here, and I love the long, drapey effect they have. I also love the fact they are wearable and also artistic however they are used.
