My handle the custom wpi device.
WPI (Covers Per Inch) is a standard way of measuring the density of yarn. It permits you to decide if the yarn you have is ideal for a knitting pattern that’s written for a different yarn.
Traditionally you simply cover your yarn around an inch space, and count how many strands it requires to fill the gap. Nevertheless, it’s never a measurement I’ve had much luck with, the number of hairs you can suit simply depends on how securely you stretch the yarn, and how much you pack the yarn in. It works better with thinner yarns, but for fat fluffy yarns you nearly might as well think.
For the past few years I’ve been using a somewhat various approach to exercise wpi. Instead of wrapping you just hold your yarn over the top of a line of a specified density. So for a wpi of 8, the line is 1/ 8th of an inch wide, if you have a reference card with a range of densities of lines you can simply compare your yarn to a range of lines and discover the finest match.
No wrapping, no packing, and I appear to get much more constant outcomes.
This little tool has a set of lines inscribed on to it, covering a variety of yarn thicknesses, and an useful reminder of the variety of wpi measurements that match the industrial names made use of for yarn densities.
To utilize, just hold your hair over the gauge and find the nearby equivalent block. It really is as easy as that. I hang mine from my wheel and utilize it to check my singles on a regular basis as I spin, to assist me make my yarn more constant. There’s even a little hole to allow you to connect it to your wheel.
There’s also a small groove at the top, measuring 1 inch, ought to you also decide to measure in the more traditional way.
