Green Variations

One of the great things about natural dyeing is that you can keep overdyeing until you get the color you want.

I recently dug out some green skeins of Norne that were not exactly what I had imagined, and had been sitting in the storage basket for a while. I decided to overdye them to get as many greens as possible. So I wound skeins for dyeing and kept the last part of the skein the way it was.

One skein (skein 1 in photo below) was a medium blue from indigo overdyed with a couple of afterbaths from pomegranate and weld. They gave a rather weak yellow, too weak to match the blue tone, resulting in a quite anemic green.

Another skein (skein 12) had the same problem. Again, a medium indigo blue, this time over dried mugwort dye. I didn’t know at the time I dyed this (as I do now) that dried mugwort only gives a rater weak beige.

Then there was a skein with the opposite problem (skein 5). It’s dyed with a strong (1:1) weld and overdyed with weak indigo, giving a green/Chartreuse that’s just too intense.

Finally, there’s a skein that was actually a good color (skein 9) but I just didn’t have any plans for it. I dyed it long ago with tansy and a madder afterbath to achieve a warm yellow. I wound all the skeins into smaller ones and overdyed them with indigo, weld, and walnut hulls.

Overdyeing and then some more overdyeing, to get as many greens as possible.

Skeins 6, 7, and 8 come from skein 5 and are just overdyed with stronger and stronger indigo, and there’s no surprises there. The strong yellow base ends up as a clear forest green when the indigo component becomes large enough.

Skeins 10 and 11 are yarn from skein 9 overdyed with a bit of indigo and a bit more. Here, skein 10 was a nice surprise, a wilted green, one of my favorite shades of green. I suppose I am really revealing myself as totally ignorant of color theory, but I did not know that this type of green contains such a large proportion of red.

I made a dye bath with 12 g of weld and dyed 25 g of yarn from skein 1 in it. That turned into skein 2 – not a surprise that the forest green emerges when you lift the level of yellow to match the blue in intensity.

Then I made a dye bath with 25 g of walnut hulls. 25 g of yarn from skein 12 turned into skein 13. Again, the ignorant dyer was surprised – turns out army green is based on brown. The afterbath turned yarn from skein 1 into skein 3, another army green.

Skein 4 is yarn from skein 1, overdyed with a rather intense indigo. Here, the weak yellow base gives a really nice teal. Skein 14 is yarn from skein 12 just overdyed with a bit more indigo than it already was.

Finally, there’s skein 15. The yarn comes from skein 12, and was first dyed in the weld afterbath. It didn’t change much, so I dyed it in the walnut hull bath, which had already been used twice. Again, not much change, so I dipped it in indigo. That still didn’t change much so I left it because I ran out of ideas.

Skein 16 and 17 are both dyed with stinging nettle, said to contain a green dye. In the middle of May, I picked a big dyepot full (and they have no problem stinging through thick garden gloves) and dyed two 25-gram skeins. First skein 16, then skein 17 in the afterbath, followed by modification with a bit of iron. None of the skeins 16 and 17 are green but they work really well along all the other greens. Here they all are, along with an indigo-dyed skein, wound in cakes and ready to knit:

All the green yarn cakes, ready to knit.

I am experimenting with knitting very short scraps of all these colors together, more about that another time. So far, it looks like this:

Norne cut in short scraps and knit – color changes by doubling both the new and the old yarn.

But the search for greens doesn’t stop here. In addition to stinging nettles, May is also full of landscapes covered by wild chervil and broom.

I tried dyeing with common broom last year, but picked the plant too late in the season and got very little color out of it. In their “Dye Plants and Dyeing”, Cannon & Cannon write that flowering stems of broom should be harvested in April or early May. I managed to pick them late in May, which is probably fine since the book is English and most of England is south of Denmark.

On alum mordanted Fenris (pure wool), common broom gives me the greenish-beige that Cannon & Cannon promise. They show an almost black with copper, so I tried modifying with copper water for a few minutes. I have a jar that contains the innards from an old wire in household ammonia, and I just added a bit of it. This gave a very pretty green, which is leaning towards brown.

Wild chervil (also picked in late May) gave the expected fragile yellow with a touch of green. To some eyes nothing special, and for sure, there are many ways to get such tones. But I do find it lovely, it just captures the freshness of spring and early summer. Modified with iron, the color darkens and completely looses the freshness.

Yellow and greens dyed with common broom and wild chervil. The large skein on top is dyed with wild chervil, the one below the same but modified with iron. The third skein is dyed with common broom, the fourth common broom and copper.

Beige Again (Walnut Shells)

I lived in Grenoble for 2 years, and everybody there is always talking about walnuts. The region is famous for its walnuts – noix de Grenoble. But I have to admit that I didn’t actually see any nuts growing, nor did I eat very many of them while I lived there…

So one day here in Denmark, when I saw a big bag of noix de Grenoble at the supermarket, I just had to buy it. The nuts are eaten a long time ago, but I remembered reading somewhere that the shells can be used for dyeing (in addition, of course to the well known dye found in walnut hulls, but that’s another story).

I like the idea of salvage dyes, the dyes you find in something you would have just thrown out. So here they are, about 500 g of walnut shellswalnutshells

Following information from this article, I soaked the shells in water a couple of days, then boiled them for two hours. The next day, I removed the shells and simmered a 10 g alun-mordanted test skein in the dye bath for about an hour. As usual with browns, it looked good while in the bath, but after drying, what I have is just another beige skein:

Useful for color knitting, but not very exciting by itself. I had hoped to obtain a deeper brown, but that is, in fact, a difficult color to obtain in natural dyeing.

Possible improvements I don’t see any – other than forgetting about the walnut shell and befriending someone with a walnut tree, so I can get my hands on the hulls

Last year, I did get good browns from mushrooms. Here is my fresh weakly beige walnut skein next to a very nice brown from last year:

brownandbeige

The brown skein is dyed with a mushroom that is quite abundant around here. I’ve typed it as Ischnoderma benzoinum (gran-tjæreporesvamp) with the help of my Swedish book “Färgsvampar & svampfärgning” by Hjördis Lundmark and Hans Marklund, but it could also be its relative Ischnoderma resinosum (fall polypore, tjæreporesvamp in Danish) . I don’t have a picture of the mushrooms I used, but I’ll look for it again next fall.

Jeg har afprøvet farvning med valnøddeskaller, men det giver kun en svag beige farve. For at få en god brun fra valnødder, så skal man altså have fat på den grønne del der sidder udenpå selve nødden. Jeg har desværre ikke noget valnøddetræ, men sidste år fik jeg en god brun farve med tjæreporesvamp.
