What I've Learned About Tracking

Actually, I've learned a lot, especially from all the helpful comments on my "Placemats?" post. There were so many positive responses to the textured look that tracking gave to the placemats, that I had to stop and think about this for awhile. Just why was I disappointed with how they can out? Two things have come to mind: preference and expectation.

As Taryl pointed out, much of how we react to things (in this case my placemats), has to do with differences in taste. If truth be told, I would have to say that my personal tastes run toward casual. I like a comfortable, welcoming, country natural look. So in one way, the tracking appealed to me. But as Valerie mentioned, not everyone likes the casual look of such a fabric. The intended recipient of these placemats is pretty much opposite to me in taste. Her preference is for the more formal, classic look. My dismay stemmed from the fact that the end result didn't meet my expectations.

Bspinner commented, "Amazing isn't it how what we put on the loom isn't always what comes off?" As weavers we know this! So why should I be surprised that my weaving sometimes surprises me? The unpredictability is one of the things that keeps weaving interesting to me. I love what Bonnie said, "I think of it as a gift from the yarn." Well put!

On the other hand, I agree with Alison, that it would be nice if we could predict and exploit. Is that possible I wonder? I have an idea in my head that if I can gain enough experience and knowledge about weave structures as well as yarns, then I'll have a greater degree of control in planning my weaving projects and their outcome. Even if this is true, I realize that the element of the unplanned outcome will still be there from time to time.

So what have I learned about tracking?

It only occurs with plain weave and only after the fabric has been agitated in water.

Textil pointed out that the sett is a factor. The more open the sett, the more room the threads have to twist. My sett (16 epi) did result in a somewhat open weave. Even after washing it is not a dense cloth.

A copy of Weaving & Drafting Your Own Cloth.Peg confirmed that the yarn also has a lot to do with it. In fact, she recommended Peggy Osterkamp's third volume in her "New Guide to Weaving Series", Weaving and Drafting Your Own Cloth.

It just so happens that I recently purchased this book, though I really haven't had a very close look at it yet. As Peg pointed out, on pages 166 to 169, there is an extensive discussion on tracking, including what causes it and how to prevent it. In reading this section, I learned that in order to prevent tracking in this fabric, I should have set it before washing and drying.

The process of setting the fabric is referred to as "crabbing," which uses heat to shrink the yarns by relaxing their inherent twist. Once set, the fabric can be washed without tracking occurring. Peggy's book describes two ways for the handweaver to do this in the home setting: in a washing machine with the hottest water available and without agitation; or with damp pressing cloths and a very hot iron. The idea is that tracking won't occur if the item is never washed in hotter water than was used for crabbing. Commercial cloth is boiled while under tension, something which probably isn't convenient for most of us, though the book does describe how to do this.

For my placemats, the tracking is permanent, though pressing can help temporarily, especially if the fabric is pressed while still damp. Peggy did mention that after subsequent washings the tracking should be less, and indeed, Kim confirmed this with her own experience.

So, how do they actually look with the dishes I wove them for?

Place setting on one of the placemats.
From a distance it isn't noticeable.

Close up showing the tracking is subtle but still visible.
Close up it is still there, though subtle after pressing. Then too, Jacqui reminded me that if the fabric were smooth and slippery, it would be less suitable for placemats.

Still, I'm not sure if these particular placemats are suited to the dishes. However, perhaps I'll just let the recipient decide. I know that she'll appreciate that I handwove them with love. Hopefully, that is the important thing in the end.

Placemats?

It's been awhile since I've blogged about weaving. This is partly because a lot of other things have popped up, but also because I've had my last weaving project off the loom for awhile and have been wondering what to do about it.

About a month ago, I posted about preparing to weave some placemats (that post here). Weaving went well, but once the fabric was off the loom and machine washed and dried, I discovered that it looked like this:

Close-up showing tracking in weaving yarns.This is plain weave with 8/2 unmercerized, unbleached cotton. The diagonal geometric textured effect was totally unplanned and not exactly what I was looking for. As I puzzled over it and whether or not I liked it, I vaguely recalled that this phenomenon is called "tracking."

Finally I decided to see what pressing would do. This is what it looked like after that....

Pressing didn't completely remove the tracking.As you can see, this did not completely eliminate the effect. I admit that I wondered whether I might have gotten better results if I had put more time and effort into pressing. On the other hand, my plan for this fabric was easy care placemats as a gift. I doubted that the intended recipient would be willing to go to very much trouble to keep them smoothed out.

Still, I puzzled over what had caused it and how to prevent it in the future. At first I figured that it must have something to do with the type of yarn I'd used. So I googled, "weaving tracking" (without the quote marks). From that I found Holly Shaltz's web page, in particular an article entitled "Plying a Balanced Yarn". From this article I learned that tracking is related to unbalanced yarn.

To be honest, I don't know a lot about commercial weaving yarns. I took a closer look at the yarn I'd used .....

Close up of the yarn I used in this project...... and observed some inconsistencies in the twist. I never would have thought to check that out first, but it does confirm the wisdom of that well-worn (if not somewhat dreaded) phrase, "Sample, sample, sample."

So. I will definitely make a sample the next time I use this yarn, which will probably be mixed with other colors and brands of 8/2 unmercerized cottons. As to the placemats? I'm not sure. I reckon I'll move on to Plan B, as soon as I figure out what Plan B is.

Another Shetland White

OK. So here is the information on that Shetland yarn I was plying when I showed you how I ply from a center-pull ball.

A few locks from a white Shetland fleece sample.This dual coated fleece measured anywhere between three and seven inches. The crimp in some places was nonexistent (as you can tell from the photo on the left), but in some staples it measured four crimps per inch.

Besides being loaded with vegetable matter (VM), the most noticeable characteristic of the raw fleece was that it had a thick, matted looking layer of yellow at the butt ends of the staples. Fortunately, this separated easily, though it was greasy enough that I decided to wash it before removing it all.

Since I had parts of two different fleeces in the bag and the white was dirty enough as to be indistinguishable from the fawn, I decided to wash them together and sort them out afterward. When I discovered that I didn't have enough mesh bags for it all, I also decided to try this method of machine washing.

The result was beautifully clean and fluffy. I could easily separate the two colors and decided to spin the white first. I used my dog comb to comb out the second cuts and much of the VM. (Next time I have a VM laden fleece however, I'm going to try out Laritza's method of dealing with it!)

I only had to run it through my drum carder one time to prepare it for spinning. With that it was delightful to spin (except for still having VM to pick out), very soft and silky to the hand.

My latest Shetland yarn.This photo is not entirely accurate colorwise, but the closest I could manage with my camera (I do miss my scanner!) The singles were 30 wraps per inch, and the 2-ply is 17. Of the 100 grams of processed fleece, I ended up with more than 218 yards of yarn.

Colorwise, how does it compare to my other Shetland whites?

5 Shetland whites.Interestingly, they are all different. Until now I would have thought that white is white is white. Not so! Which makes Shetland all the more intriguing to me. I love this breed.

Plying From a Center-Pull Ball

By Leigh

I will be the first to admit that I am an exceptionally poor judge of volume. I can never put away leftovers without dirtying at least two containers; the first one I choose is always either too big or too small. Along the same line, I have never been able to judge how much to fill two singles bobbins so that I don't have any leftovers after plying. Even weighing the unspun fiber doesn't help, as my spinning isn't entirely consistent. I'm sure I'm not alone in this plying problem, but it bugs me to no end to have bobbins cluttered up with leftover singles.

After struggling with this for several years, I finally decided that I needed to learn to ply from a center pull ball. There are several ways to make these, but I learned to do it with a ball winder. I use my ball winder for balling skeins of yarn off my swift too, so it is a useful tool to have around.

I wind the singles onto the winder directly from the bobbin. The yarn I am plying here is the white Shetland from the second batch from Cathy.

Before taking the ball off the winder, it is important to find the two ends. One comes from the inside of the ball, where it was secured in a notch on the core of the winder. The other is on the outside. I knot them before removing the yarn.


Next, it is ready to tie onto the leader yarn on the bobbin I plan to use for plying.

Securing the tied singles to the leader.

I secure the tied singles to the leader by first folding them over and through the leader loop. Then I pull the knot back through the loop created by the singles. When this is snugged up, I find that the singles are quite secure. After plying, it is easy to remove the yarn from the leader by pulling the knot back through the loop. No cutting needed.


I like to use one of my cabled yarns as a bobbin leader. Cabled yarns seem to withstand both directions of twisting than do ordinary yarns.

Getting started is a little tricky, and I have to admit that learning how to do this took some time and practice. The key to plying from a center pull ball is to keep both singles at the same tension during the plying. Otherwise, the looser single wraps itself around the tauter one. This is ok for certain designer yarns, but not okay for 'plain vanilla' type yarns.

This hand position works for me.You can see the hand position that works for me in the photo on the left. The actual position of the hand isn't critical; you may need to experiment a little to find what works for you. What's important is keeping the tension of the two singles the same.

When I first start plying, I treadle enough to get the twist started, then stop to make adjustments. One ply comes from the center of the ball, and the other unwinds off of the outside of the ball, but they do not unwind evenly! That means I may need to adjust my hand position or hand movements. Actually, I move the hand holding the ball very little, if at all during plying. I just keep an eye on the two singles as they unwind, and try to keep them the same length and tension.

The first few yards are where I experiment with the number of treadles I'll need to match the 2-ply on my sample card.


Comparing the twist to the sample yarn.

My sample card contains a short piece of freshly plied yarn off the bobbin. This shows me how the yarn wants to ply back on itself to balance the twist. To figure this out for plying, I count the number of treadles for a comfortable length of yarn, and then compare. The specific length isn't important as long as it is manageable for the spinner and remains consistent. If my 2-ply isn't perfect at first, I don't sweat it because the ends of a skein are often wasted anyway.


I like the sample card comparison method of determining the amount of twist needed, as it is more accurate with singles that have been sitting around on the bobbin. Sitting yarn tends to temporarily set its twist, so unless the twist is revived, it's hard to judge how much to ply it.

Once I establish a treadle count, I can get a rhythm going.

1st count the treadles to ply....
I count the number of treadles I need for the length of yarn I'm plying,

...then pinch and feed in.

pinch the point of twist, and let the plied yarn feed into onto the bobbin. As I feed in, the singles are pulled gently from the ball. If I need to, I stop treadling in order to reposition my hands to get an even tension.

One potential problem can be if the center of the ball pulls out like (click here) this. That doesn't happen often, mostly if the singles are very fine, or the fiber somewhat slippery. In that case, it's better to make smaller balls to work with.

Another thing I like about the center pull ball, is that it's easy to take a break.......

A handy way to take a break from plying.

The center of the ball fits nicely onto the tension knob (which isn't really used for anything anyway as this wheel is set up double drive.)

Plying from a center pull ball, like spinning itself, is an activity that is learned kinestetically. Descriptions and demonstrations may be helpful, but in the end one has to learn by doing it. It is something the hands have to learn as well as the mind. That requires experimentation and practice. These in turn require patience with oneself and one's efforts. Not easy for those of us with a streak of perfectionism! Still, to me it was worth it.

SAFF

Originally, I had hoped to entitle this post "Sheep To Shawl," because that's what I participated in at SAFF this year. The WNCF/H Guild hosted a Sheep to Shawl demonstration again, and this year was the first time I took part. My plan was to take photos of every step in the process, and post them in this blog post. Unfortunately, things didn't turn out that way, mostly because the crowds were so huge that good photographic opportunities were difficult (for this amateur photographer anyway.)

I started by trying to get a pic of the shearing demo, but due to the crowds I couldn't get close enough and at a good enough angle for a good shot. Then too, the area we had to spin and weave in, was long and narrow; the long part running from the public area to a door in back. That meant that it wasn't easy to set up the spinning wheels in any orderly fashion, especially as the ground wasn't level. We were set up in a crowded, hodge podge arrangement, and with the steady stream of curious onlookers, I never could figure out how to get some good shots.

I did have fun though. Besides the shearing demo, there was a fleece skirting demonstration. We had a good number of volunteers carding and spinning. We spun worsted weight singles, which were immediately wound off onto weaving bobbins. Our weaver used these as weft on a pre-warped loom, to weave a lovely shawl. No photos of that either, *sigh*.

What I can show you however, are the goodies that followed me home. Unfortunately, this won't be your typical fiber fair eye candy, as I had decided that fiber and yarn weren't at the top of my list. Consequently, my purchases are visually boring, but very useful.

Any type of fiber is usually a temptation for me, but I decided to close my eyes to all of it and focus on some items that I didn't want to have to mail order later, and pay shipping on. I used to do a lot of mail order shopping, but as shipping costs have gone up, my mail ordering has gone down. Fiberwise however, I couldn't resist this package of silk hankies.

A stack of silk hankies purchased at SAFF
I had so much fun knitting them, that I wanted to dye some of my own and do that again. Or maybe try weaving with them.

What I mainly wanted to focus on were dye supplies. I have done very little dyeing these past two years, but now with the prospect of moving to a larger place where I can have room to set up and get outdoors, I want to get back into dyeing.

Dye supplies
The tall bottle on the back right is supposed to be Synthrapol. It isn't. It's Retayne, which isn't the same thing. I just noticed this when I set up for the photo! Grrrr. Don't ya just love it when someone shelves an odd bottle without watching where they're putting it. *sigh*

The other items include a few Cushings dyes, a pound of alum, 4 ounces of cream of tartar, and a Procion Starter Set from Earth Guild. I got the Procion kit because I want to experiment painting some cotton warps. All my dye experience has been with wool and silk, so this will be something new for me.

RBS front with buttonsThe other thing I looked for and found, was buttons for my Rare Breed Sweater, which I was unable to find locally. This project has been set aside since last April, when I completed everything but the neck and front bands. I knitted the neck band last week, but had to wait until I got some buttons before I could knit the front bands.

I don't know why, but I always agonize over choosing buttons. I had something sheepy in mind, but wasn't able to find anything with this theme that I really liked. I know that buttons can either compliment or distract from a finished project, so I am usually hesitant when it comes to fancy buttons. Most of the time I opt for something plain, just to be safe. I really liked these however .....

What do you think? Are they a good choice for this sweater? Knitting on the button bands will commence soon.

So that's it. That's the SAFF report. It was a fun day with beautiful weather and good friends. I thoroughly enjoyed myself.
