Unraveling a knitted project is never an easy task, and it often leads to dropped stitches and wasted time. However, knitting with the Addi SOS cord allows for the effortless insertion of a lifeline as you knit. To open the lifeline eyelet, simply grasp the cord on each side of the eyelet and press together. Thread your lifeline yarn through the eyelet, and continue working as normal. When not in use, the eyelet collapses on itself and disappears into the cord.
