These Earth Silk spools are made by hand in our Seattle studio. Our 100% silk hand dipped, bias cut ribbon dyeing process produces a unique look with subtle qualities that cannot be found in traditional ribbon dyeing. Our process creates almost zero waste and generates a lasting work of art. Orders of under 7 yards will be sent flat, bagged and carded. Orders of 7 yards and above will be sent on a spool. These silk ribbons are colorfast (after washing) washable, dry-cleanable, 100% silk and are bias cut which gives them nice body or stretch. We highly recommend ordering samples (which we send for free!) if your project is colour sensitive or if you have never worked with bias cut silk. We also recommend washing a sample to see how it behaves before working the silk into anything that may be exposed to water. The cut on the bias means in a continuous spool; there is a seam every two yards and the raw unfinished edges will naturally soften or fray with wear. Unlike other companies, we finish our seams with silk thread to create a more seamless appearance throughout the spools. In conventional dyeing the yarn is first dyed in a vat and then loaded onto a loom where the strands are woven together to form the ribbon. In this hand dyed method the action happens while the bias cut spool is tightly wrapped, that pressure resist influences where and how the dye is absorbed and can produce a shift in colour from the inside of the roll to the outside. For cut yardage sales, the silk is carded and sent flat, up to six yards. Orders of seven yards and above are rolled onto a spool.
