Looking for a green alternative to leather? Maya Romanoff’s new Polyhide Lightning is made of polyurethane and has a metallic effect. Because it’s backed with rayon, it’s flexible enough to be used as upholstery (though it’s meant as a wallcovering). Find this and Maya’s new flexi mother-of-pearl brick (thinner and more flexible that the original design) at the company’s new showroom in the Mart.
