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 always the important factor. Likewise, when substituting yarns, consider the number of plies, gauge, drape and fibre content.
