I’m not completely satisfied with the warp yarn I have on the loom for my box project: i.e., samples. I’ve been constantly consulting the Sett Charts in the back of my book, Winding a Warp & Using a Paddle for other possibilities.
Here is the sett chart for linen. There are a total of 14 pages of charts. Half are for plain weave and half are for the same yarns for twill.
What has consumed me this time in checking the charts is comparing the sizes of yarns to see what I can find that will be a good size but also can work on a very, very dense warp. Since there are 4 layers, the sett (ends per inch, epi) will be 4 times what it would be for a single layer. If one layer is 16 epi for example, the total sett will be 16 x 4 = 64 epi. Ideally, I’d like something around 1500 ypp (yards per pound).
The part of the sett chart that I’m interested in at first is how many yards per pound because that can give me the information I need to know the size of the yarn.
In my case it doesn’t matter if I look at the Plain Weave or Twill charts because I am mainly interested in the size of the yarn, the ypp. However, it is important that I’m looking at the charts for linen. The numbers and sizes vary greatly with the different fibers. See my previous Tip on Yarn Count. (Sept. 24, 2011)
I have a nice yarn I might like in my stash. With this Yarn Balance, I can find out how many ypp and go from there. This valuable scale used to be called a McMorran Balance. Here’s an example of how the balance works. Say the length of the yarn that balances on the scale is 21 ½”. Multiply that number by 100 to get the number of yards there are in a pound. In this case, you get 2,150 yards per pound (21.5 x 100 = 2,150). Another balance is available for meters/kilogram, too.
You can compare two yarns quickly to see if they are the same size by hooking them together as if you linked your two index fingers together. Hold one set of yarns between your thumb and index finger. Twist the other two ends so that both sets twist. If they both feel the same, they are close to the same size.
Note: The term grist is sometimes used when talking about yarn size. For example, one might say, “I want a yarn of the same grist as this other yarn for my project.”
This worksheet to find the yards per pound is in my book, Weaving for Beginners.
This chart is helpful and is also in the beginner book.
These calculations were worked out using Ashenhurst’s Rule. The rule and exceptions are in both books, Weaving for Beginners and Winding a Warp & Using a Paddle and in several of my previous tips.
