*The above guidelines reflect the most commonly used gauges and needle or hook sizes for specific yarn categories
**Lace-weight yarns are usually knitted or crocheted on larger needles and hooks to create lacy, openwork patterns. As such, a general gauge range is difficult to determine so follow the gauge stated in the pattern.
*** Steel crochet hooks are sized differently from regular hooks. The higher the number, the smaller the hook, which is the reverse of regular hook sizing.
