Spinning from Top and the Wandering Draft Zone

For some people, spinning from a wide bit of top - like those bands that you can usually buy, at least here in Germany - can be irksome. The spinning seems to have a tendency to wander from the very tip of the top, where you started, backwards along a thin sliver of the roving. After a while, you realise that while you are still spinning smoothly, you are somewhere along the band of roving, a good bit from where it started.

When spinning on a wheel, with your roving on your lap, this can be irritating. However, you can just take off your wandering yarn with a bit of fluffy roving attached to it, place the fluff over the start of your band, and spin (and maybe wander) on.

The situation is not as nice when you are spinning with hand-spindle and distaff. Here, spinning is much easier and smoother when you really stay at the tip of your top - because otherwise, you would need to unwind the roving from the distaff, and the free tip will then hang in the way and become mangled over time. Which leads to two questions: Why does the wandering draft happen, and what to do to avoid it?

Wandering draft can happen easily on the wide band of roving because it's just that - roving, with all the fibres aligned in one direction. The drafting zone you have when spinning, especially when spinning finer yarn, is a not very wide triangle - the upper part of the "fibre triangle" that is often praised as the effect that shows your ratio between twist and draft is good. Let's say your drafting triangle has an upper edge about 4 cm wide. Your industrially prepared top is much wider than that; when I spread out mine to a thin, draft-triangle thickness, it is about 25 cm wide.

Wandering draft usually happens when you spin on the fibres at one edge of the band. Think of your band as a rectangle and start on a corner, and you are practically guaranteed a wandering draft.
Why? Because on that wide stretch of fibres that are all aligned perpendicular to the top tip (can you tell I'm amused by that expression?), it's beyond easy for your drafting triangle to eat itself upwards along the band of fibres. The fibres right above your drafting zone on the band flow into the triangle naturally. After feeding from the same bit for only a short while, the edge you are spinning from is already different from the main top front edge. If you spin here for a bit longer, your triangle wanders back, eating itself along the edge of your roving - further back than a staple length, which is the length in which you could still transition to fibres from the main top tip. In effect, you have separated a bit of the band from the main part and are now spinning along that much smaller sliver of roving. And once this separation has happened, you need to jump back to the main edge as described above, because you cannot just smoothly glide back to the  main edge.

So how can you keep from wandering like that?
There are two basic approaches that you can use: Change your style of drafting, or change the thickness of the roving.
If you watch out for the wandering tendency while spinning, you can make the drafting zone wander back and forth along the edge of the roving. This is easy if the difference between your roving width and the drafting triangle width is small, but gets harder with a very large difference. When you catch the backwards wandering early, you can gently pull your drafting zone back towards the top tip and proceed from there. Keeping the tip of top nicely (but not firmly) together into - more or less - a point makes this much easier, because it prevents you from spinning just at the "corner" of your band of roving. With a bit of practice, this control of your drafting area and shifting it before wandering draft zone occurs gets easier and easier.

The other possibility is the easier way out: Change the size of your sliver of roving. You can do that either by just gently splitting a piece of top into several portions lengthwise, or you can pull or diz it into a slimmer, longer band.
Dizzing is basically a pre-drafting process using a thing with a hole in it - any thing with a hole in it that's small enough to hold comfortably, like a small disc, a spindle whorl, a donut bead, whatever. You feed the very tip of your fibre top through the hole and then use the size of the hole to measure how much fibre is in the new, slimmer band - you gently push the diz into the top until it sits snugly, but not tightly, then grab the fibre just in front of the diz and gently pull. Push diz back along the now drawn-out fibre, pull again. I like to place my carded band on a table, clamp down on it with one flat hand a bit behind the diz for pulling, then use the other hand to pull. There's quite a lot of youtube videos of how to use a diz, though they usually show you how to diz a batt, diz from a drum carder or diz from wool combs. The process and the principle, however, are the same - using a hole of a certain diameter to help you measure out an even amount of fibre along your top. Here's just one example. I find using a diz much, much easier than pulling free-style with only my hands, but that's just me.
In addition, I feel that dizzing out will open the fibre a little already. If you are using industrially prepared wool that has been compressed or stored for a while, this does make a noticeable difference when spinning - the fibres have already been party unstuck from each other after dizzing.

You can experiment to find out how thick or thin you prefer your band of fibre to be for spinning comfortably. And combining the two approaches - learning how to keep the wandering in check and adjusting top size to spinning preferences - is the best and most efficient way. Knowing how to control a thicker bit of roving and how to prevent wandering back is a good skill to have as a spinner.
And the rest is just personal preference. I like to have a sliver that is not too thin, because I get very annoyed when my sliver breaks, and I don't mind taking a little care to prevent wandering backwards of my drafting zone; others like to have a really thin sliver where most of the drafting work is already done. There's no rule, and there's no roving size police - suit yourself. And remember to wind your fibre on a distaff for historically correct hand-spinning.

When in Doubt...

I think I am now going to invent a new blogging rule. A very easy one. It goes: When in doubt what to blog about, post pictures of yarn.

So I'm doing that. I weighed the skein of yarn yesterday, and it has 65.1 grams on its 595 metres of two-ply.

That's what the skein looks like now:

(Click the pics for the larger versions.)


And then, I just wanted to know. Exactly. So this is what happens if you match a skein of yarn with a visual survey card for threads.


Now these cards are... let's just call them unforgiving. Because you have white threads on black background, and because the threads are absolutely evenly spaced out, you can see every irregularity. You can see them so well that these cards are used for visual survey of machine-spun, industrial yarns - and those have very, very little differences in thickness.

Which means that while the yarn on the card might look quite irregular... I'm actually more or less content with the yarn. There are a few thinner-than-planned-for bits in it, and a few places where the plying could have been more even, but overall, I'd say it is pretty good quality.

And I'll probably hang that skein into my market stall with a note attached to it giving the time that it took to spin it. That should get some reactions - at least from the spinners.

Fair prices for handspun?

A while ago, I mentioned that I've done a bit of wheel spinning again for a change. After a long while (felt like forever) of spinning to more or less fill two bobbins with single, I'm now in the plying stage.

This


is what it looked like after two hours of plying work. After three and a half hours of plying, the bobbin was more than full - it had a bulge in the middle. (Of course I forgot that I wanted to take a picture. Only natural to grab the swift right away, right?) The result is 595 metres of 2-ply yarn, and it's roughly about 28 wraps per inch. Since I gave it a soak right away to relax the fresh ply, I can't weigh it yet, since it's not completely dry this morning.

However, the plying time has made me think about pricing of handspun yarn again. Six hundred metres of yarn took three and a half hours of plying. If I do a very rough calculation and suppose that spinning took one and a half times the work time of plying (I'll time a bit of spinning next time), then that means roughly fourteen hours of work total. That is one and a half workdays for sixhundred metres two-ply! And that's wheel spun with industrially prepared merino wool, so no additional prep time required plus a relatively fast and efficient spinning tool.

Fourteen hours work - now what would you pay for a skein of handspun wool like that? Probably not my normal hourly rate times fourteen, and my normal hourly rate is not very high at that. And if you look at etsy or dawanda or any other shop, stall or market, you can see handspun yarn roughly half the length offered up for less than 20 Euro. (Oh, it's hand dyed as well.) Spinning rates seem to go up to a stunning 20 cents per metre - but you can have it cheaper, too.

Now, my little wheel is not the fastest one on this earth, and I'm not trying to spin as fast as humanly possible. But let's do some maths. One hour spinning and plying time taken together will let me end up with about 42 metres of two-ply yarn. If I sell that for 20 cents per metre, I will end up with the stunning sum of 8,40 Euros for one hour of my work. Plus the material needed - and I also need the tool to work with, of course. So let's say eight of the Euros remain as "winnings".

And now there's the snag. While 8 Euro per hour might sound not too bad at the first second, what you technically are as a spinner is... a freelancer. And that means you will have to calculate so that you can pay everything yourself - your health insurance (where usually your work/your boss will pay half, if you have a fixed job), your working tools, your stockpile, your vacations; you will need to make enough money so you can cover the times you are ill or some time off that you need to recover and recharge your batteries. Oh, and maybe some day you wish to be old and pensioned? Go pay for your own pension account, then. And if you make enough money for all of that, keep in mind that you will also have to shunt off the VAT from your selling price - and that's between 15 and 21% in Europe. (In Germany, those 8,40 Euros would mean 7,05 Euros for you.)

That is much, much too little money for that work. Ask any freelancer. Go read any freelance advice column, or webpage. And too little money for work - that's not healthy, and it's not good for the economy nor society. Plus too little money for textile work also furthers the underestimation and the undervalueing of this line of work that is so widespread today.

So... provided every spinner around that sells his or her own handspun yarn (and I'd bet it's mostly female spinners here) doesn't work at least three times faster on their spinning wheels than I do... they sell their work under price. Vastly under price.

That always leaves me more than a little sad. Hand spinners, please value your work correctly!

Things happen. Yes really.

A long time ago, when I was in school, there were subjects I did like better than physics. Or mathematics.

And then, after finishing school, I started studying medieval archaeology. Hey, that's something where you don't need maths or physics for, right? That's what I thought.

This does not hold true, though, if you do heritage conservation as your "side study" course. Because once you go out and start measuring up the building, you need to lay a basic grid to start with. And that basic grid has to be right - so there's maths to calculate the angles and, even more importantly, to calculate the accuracy of your work. (Not accurate enough, you do it again.)

And you don't need physics only if you don't want to do experiments with spindles. (Or other things, probably.) So now I'm reading up on spinning physics for spinning tops and getting tutoring from the Most Patient Husband.

Which proves, again, two points that I did learn some good way back: Physics can be totally fascinating, and there's nothing that won't come in handy somewhere for doing archaeology.

All Hail the Mighty Internet.

Thank goodness it works again!

Yesterday's stint without the 'Net was not too bad, since I was able to work without the usual distractions. Plus, not reading or answering mails and not blogging did make itself noticeable in the time available for other stuff.

On the other hand, I do rely on the 'Net for some routine things, like checking translations or finding the best English word with the help of online dictionaries (I can type much faster than I can leaf through a paper dictionary) or explanations for stuff that I need to read up on (like, to take one of yesterday's examples, the definition of standard deviation). So I'm guessing that the time loss and the time gain probably even out for me.

And the reason for me to look up standard deviation? I'm working on a final write-up of the spinning experiment results, and trying to find the best way to visualise the different results and connections (or non-connections) to make it all understandable for the non-spinning reader. The article is planned for the conference proceedings of last year's OEGUF conference and might even appear in electronic format - I'm looking forward to see what medium will be chosen!

Can I have chocolate? Please?

Unfortunately, I think we consumed the rest of our chocolate yesterday while looking at graphs and fiddling with axis setups (the most patient man of them all and myself). Good chocolate. Good graphs.

And not only have I graphs, I also have visual survey cards of all the spinner's threads. Which you already know from one of the photos I posted a while ago - but now I have them all. And they are all scanned in and available digitally.

And they are huge.


This has already been resized - generously, I might add, because it did not fit into the blog otherwise. It's Spinner C, by the way - our not too experienced spinner who delivered valuable comparison data to the experiment.

Can you believe it?

After weeks (or what felt like ages, at least), rainy mornings, there is actually blue sky above today. And the weather is supposed to get a bit better during the next days. Whew!

Apart from that, I'm making things like this:


which, in this case, shows the ten thread samples Spinner E spun. E's data points lie in a group underneath the trend line for wraps per 3 cm compared to tex (which compares the weight of thread per metre to its diameter, giving a hint on how tightly spun it is).

And that tells us that E spun a bit looser than most of the other spinners, and did so consistently. Incidentally, E also has a quite "flat" spinning angle, flatter than most of the other spinners. Which perfectly fits together with soft, fluffy threads.
