* 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 |

The HAND symbol can be used to represent gauge for yarns that do not require hooks and/or knitting needles, including, but not limited to, loop yarns and arm/hand knitting and crocheting yarns. This symbol can also be used on patterns to note that tools are not needed to complete the project. |
