Experimental Spinning 2a

plied vs. drum carded

In the first part of ES2 I explored blending opposite, complementary, colors by plying them together. In this additional post I’ll take that one step further and blend those same colors on a drum carder, spin the fiber and knit swatches.

Subject – Blending complementary colors on a drum carder

Hypothesis – Taking the same colors that were used in ES2 and blending them on a drum carder will result in colors that match the Photoshop color blends created from photos of the plied swatches. i.e.

red + green
blue + orange
yellow + purple

Methods – I used the same fiber from the ES2, 50% color1 + 50% color2, and put them through the drum carder. I used 15g of each color for each batt. Every time I ran the fiber through the carder I took a photo of the carder and of the batt after taking it off the carder. For each color combination I ran the fiber through the carder 6 times. The difference between the 5th and 6th time was pretty minimal, but I was aiming for a “solid” color so 6 times seemed the most thorough test. That gives me 12 photos for each color combo, which is more than I want to put up here on the blog, so I’ll just use one color combo as an example. In addition, I made a sample using all colors together to see what that would look like too. Therefore, there are 4 samples in total.

For the photos off the drum carder I’m going to show the most striking example – yellow + purple.

After I created the batts I spun singles from half of the batt. I then chain plied the singles, soaked and hung them to dry. I knit swatches from yarn; 4 swatches in total.

When I finished the swatches I took photos (doing my best in this winter storm weather to get good light!) and then used Photoshop to blend the colors there to see what those color blocks would look like compared to the blends from ES2.

Testing – Here are the yellow+purple drum carder blend photos:

Here are the finished batts next to their plied swatches from ES2. You can already see how much impact blending the fiber has on the resulting color that your eye sees.

I think that the last photo above, with all 4 batts and swatches together, is the best color representation of the photos. I am not a professional photographer and all I have is winter light and a few floor lights to work with. But this one is pretty darned close to reality.

Here is a photo of the finished yarn, balled up and ready for sample knitting. Again, this looks to me, on my computer, pretty true color.

Here are photos of the finished swatches, next to their matching plied swatches from ES2.

I then took those photos to Photoshop, cropped just to the knit swatches of the blended fiber, and blended the colors into one. Here are the results of that, compared with the same method used on the plied swatches in ES2.

yellow + purple carded
yellow + purple plied
blue + orange carded
blue + orange plied
red + green carded
red + green plied
all colors carded
all colors plied

Results – First, I’d like to say that I was most surprised by the purple and yellow combination. Carding those colors together created a green that was nearly impossible to know which colors were responsible for it! Comparing the 2 swatches side by side shows what a striking difference thoroughly blending fibers together can make. Your eye is completely tricked into not seeing any yellow or purple at all when the “pixels” or pieces of color are so small. Maybe if we had eyesight like an eagle the blended swatch would look like a smaller version of the plied swatch. I don’t know. But human eyes are not up to the task of teasing out individual color once they are so completely combined.

The red and green blended swatch came out darker than I imagined, but when I think about it, it makes sense because both of those colors have such dark values.

The blue and orange carded swatch looks very purple, which also makes sense considering how much a strong orange is composed of a lot of red.

The swatch of all the colors combined is really interesting. Does it remind you of anything in particular? A field of flowers from a distance? Ground sausage? The planet Mars? I think the yarn is really lovely, but my husband doesn’t like it at all. I think it’s a love or hate or too weird situation with that one. What do you think?

The results of comparing the Photoshop blurred images is not really conclusive to me. I think I need to spend more time to understand the algorithm used or find another way to blur the images to “see” the colors really combined. Actually, if you look at the Photoshop blurs of the carded swatches compared to their actual swatches, the colors are very close! I think probably the more “blurred” the image is in the first place (i.e. the carded swatches) the closer the Photoshop “blur” can represent it. When the image has such big color blocks to start with (i.e. the plied swatches), Photoshop cannot really represent it as a good average. Maybe I’ll investigate that further.

Summary – This has been a very enlightening and interesting set of experiments in this edition of Experimental Spinning. I have learned that

  • Blending complementary colors can give you very different results depending on HOW they are blended (plied together vs. carded 6 passes)
  • Combining complementary colors does NOT necessarily create brown colors. Even combining all primary colors and their complements doesn’t necessarily create brown. Brown is more complex than that!
  • Fooling your eyes into thinking you see a certain color is not hard to do. This opens up a whole can of worms – or roads to explore – in regards to color blending.
  • Blending colors on a drum carder is something I want to take to the next level of precision! Stay tuned for more on this topic!

Experimental Spinning 2

In the first Experimental Spinning post I used shades of purple to demonstrate the effects of multiple plies and multiple colors on the final knitted fabric. In this post I will continue with the theme of using plying to play with color, this time working with opposite colors on the color wheel. Again, I am using a somewhat scientific structure to organize my method from start to finish: Subject, Hypothesis, Methods, Testing, Results, Conclusion

Subject – Plying Opposite Colors

Hypothesis – Plying so called “complimentary colors” from a color wheel will result in muddy brown color in a knitted swatch.

Everyone knows that mixing blue and yellow will give you green. blue + red = purple. yellow + red = orange. I have heard and read and found in dying wool, that mixing complimentary colors will often end in mud. If you’ve done any painting or fabric dying or fiber dying, you may also have had this experience. But does this always hold true? Will it hold true with simply plying them together?

First of all, what is the definition of “complimentary” color? Using the most common generally accepted color wheel, complimentary colors are those found directly opposite on the wheel. The compliment of blue is orange. For red it is green. For yellow it is purple.

Methods – I began by spinning singles in each of the 6 colors needed: red, blue, yellow, orange, purple, green. Your basic rainbow.

I used European Merino (27 micron) that is inexpensive and readily available from a local shop. It is commercial dyed. I didn’t need a lot so only spun 20 grams of each color. I spun everything for this experiment on an Electric Eel Wheel 6.0.

I then plied HALF of the amount on the bobbins with their compliments.

red + green
blue + orange
yellow + purple

Then I knit swatches with the yarn.

red + green
blue + orange
yellow + purple

I then decided to ply the rest of the singles together into 6-ply yarn to see what that would look like. My additional hypothesis was that all 6 colors together would look muddy. I had never made 6-ply yarn before and was a little nervous about handling all those singles, but it was actually pretty easy.

Testing – Testing the hypothesis is a very subjective process. Do these colors look muddy to YOU? Do they look muddy to ME? With this method, only the green/red combination looks muddy at first glance. I think this is because the value of the colors are very similar. Meaning, they are equally dark. Mixing yellow and purple in a 2-ply yarn only looks like a marled yarn because the value of the colors is so different. The yellow is so bright compared to the purple. To test this further I took a black and white photo of the yarns together. Here you can see what I mean.

from L to R: yellow/purple, blue/orange, red/green

It’s clear from the photo above that the red and green colors are very similar in value and thus more easily fool your eye into thinking they are blended together.

What if you would see the effect of the color mixing more obviously if the pieces of color were tiny pixels instead of large chunks of yellow and purple? I decided to look at the photos of the swatches in Photoshop and see what I could do there to blur the image and see what color would result.

I used the Blur filter on the photos and came up with these results. The algorithm finds the average color from what it sees in the image.

red/green blur
blue/orange blur
yellow/purple blur
6 color blur

Results – Mixing complementary colors via plying does not create a stark or obvious mud color to MY eyes. Possibly the result would be more mud colored if I had spun very fine singles and knit a swatch with 2mm needles the stitches would be small enough to make more of a muddy impact.

However, if you visually mix the colors fine enough it is clear that a muddy color results. So, if you are painting, or mixing dyes, the Photoshopped blur colors are likely what you will get as a result.

Summary – I consider my hypothesis proved right, even though my swatches were too large in their pieces of color to see the effect at first glance. Blurring the images shows the true mix of the colors when the size of each “pixel” is inconsequential. But this leads me to sub-hypothesis, and the next episode of Experimental Spinning…. what happens if you blend these same combinations on a drum carder? How many passes on the carder are needed before you see the complete blending of colors, matching more or less the blurred images above? Do we still end up with mud? Does blending on a drum carder mimic blending dyes in a dye pot? I’ll let you know in a couple of weeks.

Side note – I have fallen in love with the 6 ply multi-colored yarn. I was surprised how easy it was to ply so many singles together and I’m very happy with the result. It’s not ropey. Not terribly bouncy, but not hard either. I’m very tempted to spin up some more singles and ply enough to make a hat. I think it would make me smile every time I put it on. My advice to spinners – go for lots of plies and see what happens! It’s only wool after all. You are the boss of your spinning.

Experimental Spinning – 1

Corriedale fiber

For the past couple of years I’ve been thinking about writing a book. About spinning. Because I have so many questions and I want to take readers on a trip with me to find the answers. Writing a book feels very daunting so I’ve decided to take it in pieces, starting with blog posts, and starting with this one today, which is why it is titled with the number “1”. There will be many more of these spinning experiment posts, put into a separate category on the blog called “Experimental Spinning” so as not to confuse it with just every day normal spinning. 🙂

I’ve already got many topics outlined and summarized like chapters in a book and I hope that they will fit nicely into blog posts. Otherwise I’ll chop them up to fit.

The format for each topic will be the same: Subject, Hypothesis, Methods, Testing, Results, Conclusion. For anyone who has taken science classes in school this should look familiar. It’s a way to structure this work and make it easy for someone else to follow the steps and see if they get the same results, or to modify the experiments to test a similar hypothesis. I hope this will make sense as we go down this road together, my readers and I.

OK, now that I’ve set the scene…

Experiment 1 – Effects of multiple numbers of plies on color and texture

Hypothesis – 3-ply yarn is the best for knitting/crochet. It is round and bouncy. Colors play well together in 3’s. 2-ply is less round, 4-ply is ropey and 5-ply even worse. More than 3-plies in multiple colors is just not pleasing to the eye. Therefore, 3-ply is the best yarn to make when planning to make garments from spun yarn.

Methods – As you can see from the photo above, I have 5 similar colors of fiber. This is Corriedale that I bought from World of Wool (WoW) in the UK. The colors range from dark to light, blue-ish to red-ish and a basic purple. All of the colors are listed in the “purple” category by WoW.

Create 4 yarns, from 5-ply to 2-ply.
1. Create 5-ply yarn: Spin 5 x 10g bobbins, 1 of each color, as lace weight, and ply them together. Wash and set the yarn. Look at the yarn created and choose the 1 color that stands out and remove it from the next round of spinning.
2. Create 4-ply yarn: Spin 4 x 10g bobbins of the 4 remaining colors and ply them together. (I chose to remove the lightest color from this round, using purple, red-ish, blue-ish and darkest colors.) Repeat the washing, setting, reviewing and deciding which stand out color to remove for the next round.
3. Create 3-ply yarn: Repeat step 2 for the 3-ply spin. Spin a little thicker single to try to keep the total grist the same. (I chose to remove the blue-ish color from this round, using purple, red-ish and darkest colors.)
4. Create 2-ply yarn: Repeat step 3 for the 2-ply spin. (I chose to remove the darkest color from this round, leaving the purple and red-ish colors.)
At the end of these steps there should be 4 skeins of yarn, a 5-ply, 4-ply, 3-ply, 2-ply, all different combinations of colors, as close to the same grist as possible.

Testing – The best way to test the results of the method is to knit swatches of each yarn. The photo below shows the swatches from 2-ply on above, to 5-ply at the bottom of the photo. I used size US4/3.5mm needles for all the swatches. Each one measures about 6″ x 5.5″ (15 x 14cm). They were all knit: CO 32 sts; knit 4 rows; (seed st 4 sts, stockinette for 24 sts, seed st 4 sts) for 4″/10cm; knit 4 rows; bind off. Weave in ends and steam block.

You can see that from the 5-ply I removed the lightest color. From the 4-ply I removed the blue-ish color. From the 3-ply I removed the darkest color. What remained in the 2-ply was the purple and red-ish colors.

While I knit the swatches I developed a ranking/testing method that will hopefully show the “winner” of this test and whether or not the winner is the 3-ply that I hypothesized it would be. There are 8 categories and each one will be ranked from 1-5, 5 being best.

Below are close up photos of the swatches, from 5-ply to 2-ply.

5 ply – All 5 colors used
4 ply – Darkest, blue-ish, red-ish, purple colors used
3 ply – Darkest, red-ish, purple used
2 ply – Red-ish and purple used

Conclusion – Obviously this is not empirical testing and the results are subjective. These are my opinions about my own spinning and knitting and color choices. According to the ratings, the hypothesis holds and 3-ply is the best yarn for knitted fabric and mixed colors (of similar hue).

What surprised me? I was surprised by how nice the 4-ply yarn is. I think that apart from the extra time to spin an extra bobbin (as compared to 3-ply), it would have rated right up there with 3-ply yarn. It is NOT ropey, but still soft and bouncy and the chosen colors look nice together. It is not too busy in my opinion.

An observation about the 5-ply yarn – I found that it felt ropey in my hands and the yarn was kind of splitty, meaning that it was easy to split it with your needle while trying to knit. If you have ever knit with Wolmeise sock yarn, you know what I mean. That yarn is 6 plies of wool, however it is so ropey that it feels almost like cotton. Based on that yarn knitting experience, and this spinning experiment, I am coming to the conclusion that anything more than 4 plies is probably not going to be bouncy and lofty.

An observation about 2-ply yarn – The 2-ply yarn is rated so highly in the testing mainly because it is very efficient and easy to make. If I were to give a weighting factor to the table, I would weight the resulting fabric higher than efficiency (I’m spinning for myself after all, not for money) and maybe the 4-ply would have come out with a higher ranking than the 2-ply. The 2-ply fabric is nice, but not as bouncy and kind of boring in the depth of color. I also made a 2-ply using the darkest and lightest colors together to see what that would look like (bonus testing) and it’s really your typical marled effect.

marled 2-ply (darkest and lightest colors used)

In summary, if you are looking for fabric with nice depth of color and nice round crisp stitches, go for 3-ply. If you are just a little more adventurous, try a 4-ply.
