Average Yarn Tensions & Yarn Weight Uses

Yarns come in all different thicknesses, and these are referred to as ‘yarn weights’ or ‘ply’. There are a few different names given to each of these yarn weights and different yarn weights are suitable for different projects. The weight of yarn effects the size of the finished knitting or crochet, and also the hook size or needle size that needs to be used. We’ve put together a handy guide for each tension, as well as a chart which shows the information at a glance.
