*GUIDELINES ONLY: The above represent the most frequently used gauges and recommended needle or hook sizes for specific yarn types.

** Lace weight yarns are typically worked with larger needles or hooks to achieve airy, openwork designs. As a result, it's challenging to define a precise gauge range. Always refer to the gauge provided in your pattern.
