REGIA PAIRFECT – A new dimension in sock knitting! This innovation by REGIA makes it incredibly simple to knit two self-identical patterned socks from one skein. It's very simple: the yellow starting thread - which comes from inside the skein - marks the start of each sock. Simply cut the yellow starting thread and start knitting the first sock. Once the first sock is finished, unwind the thread to the next yellow starting thread and cut it. Then simply knit the second sock.
