At the last October meeting everyone had a go at measuring tension swatches and working out the stitches and rows for their chosen pattern shapes. Liz explained how to use the green ruler and covered the other rulers for different gauge machines and knitting. The rule has stitch gauge on one side and row gauge on the other.

The board surface is rough like an emery board or sandpaper and keeps the swatch flat and still whilst being measured. They used to be on sale in the days when machine knitting was very popular. One can be hand made by attaching sandpaper to a firm card or thin board.
