Double Knitting and Light Worsted weight is in general the most widely used yarn. Suitable for most garments and relatively quick to knit up. The recommended needle or crochet hook is 3.5mm to 4.5mm. The DK yarns that are in stock are suitable for most standard Double Knitting Patterns, so will adapt to your favourite pattern for your project. It is advisable to always make a 10cm x 10cm square to check tension to adjust your needle or hook size if required.
