Wraps per inch, or WPI is a way to determine the weights of any yarn.
Simply take a pencil, dowel, or ruler and mark off an inch. Then wrap the yarn around your pencil, dowel or ruler until you get to the inch mark. All that’s left is to count how many “wraps” and compare it to a yarn gauge chart.
There’s a great treatise on this method, here at Achemy Fiber Arts, as well as a chart outlining how many wraps it takes to determine different thicknesses of yarns. It’s a great way to gauge handspun yarns and other non-standard yarns.
Fall will be here before we know it, and that means there are holidays coming right behind where we might be entertaining at home. It’s always fun to have a hand knit touch in your home for other people to see, and if you’re going to be in the kitchen all day you might as well have some nice knit dish cloths to use.
