Lace knitting is one of the most challenging types of knitting because of the difficulties involved when you have to unravel one or more rows to fix a problem. To keep your knitting from unraveling further than you want, knitters often insert a lifeline into their projects. Although it is possible to insert a lifeline using a needle and thread or dental floss, an easier technique can be accomplished using your HiyaHiya Interchangeable cable with a lifeline hole. For more information about lifelines, please see our Knitting Tidbits page Add more flexibility to your HiyaHiya Interchangeable Set with additional cables! Small cables are designed to fit HiyaHiya Interchangeable Needles size 2-8US/2.75-5mm
