I used to hate plying my handspun.  Plying adds strength and durability to a yarn, so it’s worth doing in theory.  I love knitting with a good two-ply yarn better than a singles yarn.  (Malabrigo Worsted or Crystal Palace Mochi are commercial examples of singles yarn.  Knit Picks Palette is a commercial two-ply.)  So, why did I hate plying and what changed my mind?

 

Lots of spinners dislike plying.  Most dislike it because it takes longer to complete the yarn (you have to spin twice the length of singles and double them up to make a two-ply.)  I don’t mind the extra time; what I disliked was that the finished yarn never turned out the way I wanted it too.

 

Now, when you’re spinning the singles, you’re supposed to pause occasionally and perform a “ply back test.”  You let the strand twist back on itself, producing a short bit of two-ply yarn- a preview of the finished yarn.  If the little bit doesn’t look or feel the way you want the finished yarn to look or feel, then you can change how much twist you’re putting in to achieve the right properties.  I do the ply-back test often enough and generally end up with a sample that I’m happy with.  If you’re smart, you clip off a good sample section and attach it to something near your wheel or spindle to remind yourself what you’re aiming for.  (I’ll admit, I’m usually not that smart.)

 

You perform a similar test on the plied yarn as you ply  (let’s call it a “twist test,”) but this time you don’t want the yarn to twist on itself.  You want it to hang down nicely straight.  If it twists on itself, that means you have too much or too little plying twist.  You want a “balanced” yarn that doesn’t twist when you’re finished.  An over-plied yarn can distort your knitted fabric.  I did this test too and adjusted my twist to achieve a balanced yarn.

 

But then why did my yarn always look under-plied and nothing like my pretty ply-back sample?  If I plied to the sample, the yarn twisted back on itself like crazy- theoretically leading to a poor knitting yarn and a waste of time and fiber (for me, anyway; you can do interesting things with over-active yarn, but it’s not my thing.)

Then I came across this post about good-looking two-ply yarns on Ask the Bellwether.

 

When you’re done spinning your singles, the standard advice is to let them sit for a few days.  This lets some of the twist energy go “dormant” and makes the singles easier to manage.  The other reason is that you never finish all of your singles at the same time (it’s more of a sequential activity,) so one single is always older than the other.  Letting them sit for a few days evens them out so that you’re not plying a fresh energetic single with an older dormant one.  You ply with stale singles, if you will.  But when you do the ply-back test, the twist is still new and energetic. See where I’m going here?

 

The ply-back test, which you used to figure out how you wanted the yarn to look, used fresh singles.  The twist test on the plied yarn uses stale singles.  So, as the Bellwether points out, if you insert just enough twist to get a balanced yarn when plying the stale singles, you’ll actually under-ply.  Every time.

 

Once I read that, I couldn’t wait to finish spinning some singles to try this out.  I plied to my sample (which had been made with the ply-back, fresh single) instead of to a balanced yarn.  The finished skein twisted something fierce, but I dropped it in it’s hot bath anyway.

It bled quite a bit (took three rinses to get the water to be only tinted purple!)  Yes, there’s another skein in there with it, which luckily was brown so didn’t get any dye on it.  I need to remember to always wash skeins separately.  I just know I’ll put a red skein in with something white sooner or later and then I’ll be sorry.

 

What came out of that sink, though, was beautiful.  The dried skein didn’t twist back on itself at all and I finally had a yarn that looked and felt right.  It knits up lovely.

I have since replicated these results with three other fibers:

So, what have we learned?

 

Ignore the twisting skein.  Follow the sample.  The sample will set you free.

  1. That turned out very well! I’m glad the post was useful. Another thing I do is check the ply-back during plying (since you’re plying stale singles, the plied yarn also twists back on itself) — I can use that as a gauge that I’m putting the same amount of twist in the yarn as I go along, if I check that the plying ply-back stays the same.

    That’s a great idea- I’ll have to do that next time I ply! I still have a lot to learn, but it feels great to be producing usable yarn.

    What blooming good and sensible advice. I’ve just spun up some laceweight silk/merino blend that cost more than I can afford to mess up and will leave the second bobbin to its own devices for a couple of weeks. The yarn in a similar blend that I previously spun and plied within a couple of days did have some pretty ‘lively moments’ (although quite usable) but this is definitely worth a try.

    I often spin in a group and find that when there’s an interesting and controversial topic of conversation going on, more twist gets into the singles!

    Many thanks!
