| Needle & Yarn guides |
| This page has been provided to help with conversions between needle sizes and yarn weights. The needle sizes provided in knitting patterns should be considered a starting point, rather than a fixed rule, as the gauge is the important factor. Likewise, when substituting yarns, consider gauge and fibre content. |
