The lifeline cords allow you to mark and secure a line when knitting complicated patterns, if you need to unravel some rows. Available lengths 60cm, 80cm and 100cm (US 24″, 32″, 40″). If a complex pattern is knitted and a mistake is made, it is difficult to unravel the knitted part again, as the stitches are hard to check. It is simple though with the addiSOS – the lifeline thread can be simply fed directly into a row of stitches, using a slitted thread, which limits the extent to which unravelling takes place. Applied for a patent. Hold the rope and press the rope together to make the slit open. Thread your auxiliary thread through the opening and continue to work as normal by hand.
