The Large Knitting Needle is ideal for finding the rows in both the length and width (warp and weft) of a cut-pile carpet.  When used properly, the slightly rounded tip finds its way between the rows of yarns and then the wide shaft of the Knitting Needle spreads the yarns away from each other so that you can make a perfect cut following the rows in seaming or sectioning without cutting any face yarns.  

You will find this to be one of your favorite row finding tools for cut pile carpet in your tool box!
