The Daily Swatch shows one piece of vintage fabric (almost) every day. Themes change periodically. You are welcome to add your own examples of the theme to the True Up and/or Vintage Fabric Flickr Pools.
Vintage plissÃ© floral fabric, from the collection of Sarodeo on Flickr. PlissÃ© is lightweight fabric treated with a caustic soda solution during production that shrinks the fabric in parts giving it a bumpy look (stripes here, but it can be all over). The effect is similar to seersucker, which gets its texture from the weaving process.
