The knitting patterns for these adorable jumper and cardigan twinsets for kids are originals from the 16 January 1965 issue of Woman’s Weekly.
The original instructions say; One thing leads to another and when we designed these indispensable twinsets we made them in three good sizes - to fit up to a 28-inch chest. Raglan sleeved, both jumper and cardigan have fancy borders, former boasts a cosy collar too. Work at a tension of 7 stitches to 1 inch in width over the stocking stitch, using No.10 needles, to obtain the measurements given below.
