Rowan Original Denim, 03 - Black Fiber Content: 100% Cotton; Net Weight: 50 g / 1.75 oz Yarn Weight: 3 - Light/DK; Length: 92 m / 100 yards Needle Size: 6 US, 4.00 mm; Gauge: 20 sts x 32 rows = 10 cm / 4 in Texture: Plied. Care: Machine washable, low iron Rowan Denim, as with other indigo dyed textiles, fades and ages with washing and wearing. During the unconventional dyeing process only the surface of yarn is dyed leaving the core white. Most of the color loss takes place during the first wash when all the loose dye is washed out exposing the core. The knitted pieces will also shrink in length during the first wash. This tightens the knitting adding emphasis to cables and texture giving the finished garment its unique look. Because the dye is only surface dye, during knitting the colour will come off onto your hands. This will wash of very easy but it is advisable to protect your clothing or wear something dark.
