Do you want your project to be warp-facing, weft-facing, or balanced? Other weaving drafts and weaving structures will have other starting points, depending on how wide your weft floats will be and how many warp threads the weft skips over at once. The starting point for a twill weave is typically WPI * ⅔. What weaving draft do you intend to use?Īs stated above, the starting point for a plain weave is typically WPI/2. If, in contrast, you wanted a dense heavy placemat, you might take the same yarn and sample it at 14 or 15 EPI, with a heavy beat of 14 or 15 PPI. If you actually wanted your scarf to be light and airy, you could sample with a more open sett of 10 ends per inch, and weave your weft with a light touch so your PPI was also around 10 EPI. So if, for example, you are planning a plain weave scarf and you discover that your yarn has 24 wraps per inch, your starting point for the sett would be 12 ends per inch. The heavier your EPI and PPI, the denser your finished fabric will be. How dense do you want your finished fabric to be? Enjoy the sampling process!Īs you set out to sample, here are a few other things to consider when deciding on your sett. While everyone wants to get right into weaving, sampling is a big part of the creativity of a new weaving project, and can save you time, money and heartache by discovering what works and doesn’t work before you weave your entire project. You should use these guidelines to inform how you begin your sampling process.

These are some basic guidelines for how to determine your EPI/sett. Weaving Samples & Other Tips for Determining Your EPI/Sett

Count how many times you wrapped the yarn in one inch. Using a ruler or smooth stick (like a pick-up stick) with markings 1” apart, wrap the yarn snugly for one inch with no space between the yarn, but make sure you aren't scrunching up or overlapping the yarn. But the label from your yarn is long gone or never had one, so now what?Įasy! Find your WPI to calculate your EPI to get your sett.įirst, let’s find out the WPI of your mystery yarn. How do you know for sure whether or not you can substitute it? You can start by comparing the recommended sett of the project with the recommended sett of your yarn. Say you’ve just downloaded one of our weaving patterns and you have some yarn in your stash that you think will work. Sett: the distribution of warp ends in your fabric, usually over one inch (hence epi = sett). It is often used interchangeably with sett (see below) PPI: picks per inch, the number of weft threads in one inch of woven fabricĮPI: ends per inch, the number of warp threads in one inch of woven fabric. WPI: wraps per inch, the number of times a yarn around a 1' space on a ruler or pick-up stick.

For a full glossary of weaving and equipment terms, check out this blog post. Here are a few of the weaving terms we'll be using in this post. When you're learning to weave, terms like WPI (wraps per inch), EPI (ends per inch), and weaving sett can be confusing! This blog post explains each of these common weaving terms, and explains how to calculate all three so you can start weaving with confidence.
