Baia do Sancho in Brazil… Its crystal-clear waters filled with turtles and dolphins make this beach one of the most beautiful in the world. SANCHO is an open-weave, double width voile made of 100% polypropylene. Using two alternate yarns in the weave gives it beautiful texture. Depending on the sought-after look, the fabric can be used both ways. The fabric is solution-dyed: the fibres are dyed at the start of the production process which avoids the use of certain chemicals and makes the fabric more resistant to sunlight.
