An unusual and interesting exhibition has just been held in London of artists textiles. It was called Styled by Design and it will re-open later this summer in Somerset in England's West Country – so others will get a chance to see it. It included textiles designed by some of the giants of 20th century art, including Picasso, Matisse, Chagall, Henry Moore, Alexander Calder, Barbara Hepworth and others. It has something important to tell us about textiles and art, something that many mainstream art critics have missed. Here's the story of Artists' Textiles and why they matter.
