Sasawashi is a combination of traditional Japanese papers with Japanese herbs that are woven in a new and creative way. The textile is supposed to be great for people with sensitive skin because it doesn't have stray fiber ends to irritate the skin and make the fabric itchy to the touch. It is also supposed to be nearly 90% UV-proof and full of vitamins.
One of the designers that is really embracing this new fabric is Linda Loudermilk--she has already incorporated it into a variety of garments in this current season, including denim.
So, next time you are out shopping and see "sasawashi" on the fiber content tag there's no more wondering!
