Why does a pattern swatch specify both stitches and rows?
Seems as though there are two dependent variables (stitches per 4", rows per 4") and only one control variable (needle size) once the yarn has been selected. Both of the dependent variables are simultaneously affected by the needle size. In other words, not enough degrees of freedom.
If the swatch stitch count per 4" is correct how can I then affect rows per 4" without changing needle size?
Seems that a designer need only specify stitches per 4" for gauge and the number of rows would then automatically follow, unless rows can also affected by something other than needle size.
