These beautiful yarn cakes are 150g/200m. They are cotton and acrylic blend (50/50). They are 'shawl in a ball' - one is enough to knit or crochet a shawl. Colours change gradually, giving you a beautiful result when knitting. The threads are not twisted, but it doesn't cause any problems when knitting or crocheting (I tried already!)
