REGIA 2-ply is perfect to darn and reinforce socks which are prone to heavy wear. Hold it together with your choice of REGIA sock yarn as you knit the heels and toes to reinforce these hard-wearing areas. Or, if disaster strikes, use it to darn any holes or snags. It is also ideal to add detail to toys and sew on buttons. Available in a broad range of solid colors, it is non-felting, hard wearing and retains its shape well. Can be machine washed up to 40° C (100° F) and machine dried.
