[1] Yarn weight is important in achieving the correct gauge or tension for a particular project and can help with yarn ...
Larger knitting needles also produce larger stitches, giving fewer stitches and rows per inch. Changing needle size is the best way to control one's own gauge for a given pattern and yarn. Finally, the knitter's tension, or how tightly one knits, can affect the gauge significantly.
