Meet the Sett Checker

To get the cloth you want, the secret is in the sett. To guesstimate sett, the spacing of the yarn in the rigid-heddle reed, conventional wisdom has the weaver wrapping yarn around a ruler for an inch, allowing the yarns to sit next to each other, not invade each other’s space, and be in a semi-relaxed state. Then you count the yarn wraps, divide that number in half, and use this result to guesstimate the yarn’s balanced plain weave sett. From here, you decide which rigid-heddle size available to you, will get you the the results you want.

Use wraps-per-inch to estimate a balanced plain weave sett

For example, say your wraps per inch (w.p.i) is 18, then your balanced plain weave sett guesstimate is 9. The most common setts to choose from are 8, 10, and 12 and their metric equivalents. You have a choice to go down to an 8 or up to a 10 to get in the ballpark of a balanced plain weave. When in doubt I tend to round up.

There is a world beyond a balanced plain weave sett, there are “close” setts where you space the yarns a little tighter than a balanced sett or there are “open” setts where you space the yarn a little looser than a balanced sett. There had to be a better way to guesstimate sett other than wraps per inch.

Meet the Sett Checker!

Use Yarnworker's sett checker to visually compare any given yarn in three different setts. It will change how you see yarn!

 

Angela at Purl & Loop and I collaborated to create a new tool that gives the weaver more information about the yarn before starting to weave. It shows you exactly what a yarn will look like in a sett of 8, 10, and 12 ends per inch (e.p.i) and it allows you to quickly compare one sett with another. This tool also allows you to see the yarn’s character when it is in a particular sett.

Not only does this tool allow me to guesstimate a balanced sett, sometimes called a tabby sett, it can also help me find a close or a twill sett and an open or lace sett. In the example above, the middle wrap in a sett of 10 is approximately balanced. You see the same about of positive (yarn) and negative (wood) space. The wrap on the right in a sett of 8 is more open and the wrap on the left in a sett of 12 is more close. By design, you can allow the yarn wrap by the logo to lay in its utterly relaxed state and compare it to the other wraps that are under tension. Based on this information, I can make a more informed decision on which heddle to use.

To use the sett checker, grab a yarn from your stash. Hook the tail of the yarn source in the lower curved notch and allow the tail to drape over the top of the checker.

To use the sett checker, start by placing the tail of the yarn source in the notch

Wrap your yarn around the checker, filling in all the sett spacing as you go.

Finish by securing the yarn in the upper notch. Cut the yarn from the source. Either let the tails hang free or you can secure the yarn on the back with a short piece of tape. I prefer painter’s tape, because it won’t leave any residue behind. Be sure to allow that first yarn wrap to stay in its natural relaxed state so you can compare it to the yarn wraps which are under a little bit of tension.

End by placing the yarn in the upper notch

You will find this tool invaluable for making smart sett decisions. It is isn’t a complete replacement for sampling, but it gets you much closer to making a good sett choice than a single yarn wrap.

Shop the Yarnworker Collection at Purl & Loop for a bevy of tools you can use for designing your cloth. A portion of the sale comes back to Yarnworker to support the school.

Heddles Up!

  1. First thought…THIS is so cool! Second thought…which sett would Liz choose for that yarn? Inquiring Maria would love to know.

    • Great question! It depends on what you want to weave. The middle sett of 10 is what I would consider a balanced plain weave. So that is what folks often think of as “sett” but there is a world beyond that. To the left is what I would consider a close sett good for twill and warp-faced weaves. To the right is 8, which would give me a more open sett for lace and weft faced weaves. The tool makes it easier to visualize and make good choices.

  2. Great idea, Liz! I’m thinking one could also weave four or five warp strands through for a real quick sample . . . hum m m m 🙂

    • If you email me your address at worker@yarnworker.com I can give you a shipping quote. Unfortunately shipping form the US overseas is quite expensive. I can check with Purl & Loop and see if any of their European dealers are gong to pick up the checker. For the Canadians, I believe Louet is doing to start distributing them to their Canadian dealers. They won’t have the Yarnworker logo on them, but they are the same tool. I’ll put a note in my newsletter as distribution plans develop.
