James C Brett Marble Chunky Glamour is the latest product from this innovative brand (November 2016). Spun in Turkey from a blend of premium acrylic and polyester, Glamour will knit to standard Marble Chunky designs the difference being that Glamour has a sparkle thread running throughout! Because of the sparkle you lose around 10% meterage per ball against ordinary Marble Chunky. A rather nice seasonal fabric for those of us who love sparkling! Machine Washable. Weight – 200g ball. Length – 270m to a 200g ball. Needle Size – 6.00mm. Tension – 14sts & 20rows to a 10cm sq. Composition – 99% Premium Acrylic & 1% Polyester.
