POLY FLASH puts a new twist and look to textile surface design offering a layered and textured look effect while adding a subtle sheen. The look of POLY FLASH looks like hammered metal - mix it up with other threads to create a depth that you can’t get with just one alone. The good news is that it sews out like a polyester thread! The result of innovative manufacturing by combining the properties and look of polyester, viscose and metal in a single thread. It is as strong and as resistant to chlorine as polyester but has the silky soft shine of viscose and the shimmering sheen of metallic thread. This speciality thread is very skin-friendly and easy to work with.
