* GUIDELINES ONLY: The above 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. Accordingly, a gauge range is difficult to determine. Always follow the gauge stated in your 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
