More Dyeing with Yellow Cosmos Flowers on Wool, Cotton and Silk

Yellow Cosmos really enjoys full sun.  For a couple of years, I've been sowing a few seeds, just to keep my stock of plants going, really. Never had enough flowers to do much dyeing and frankly, not that excited by having another source of yellow.  This year, having planted out my seedlings in a better site and paid more attention to cutting all the flowers every few days, August has provided a bonanza of bloomage, mostly bright yellow, some strongly orange.  In 2014, I blogged about my first trial, when I saw how washing dyed wool in an alkaline detergent shifted the yellow toward red.  This summer, weighing and saving flowers in a temporary solar jar has set me up nicely for a bit of further experimentation.
Half a dozen plants have provided about 70g of fresh flowers each week and are still covered in buds, though the two in terracotta pots are always thirsty and droop alarmingly if I neglect to water them.  Pouring some fluid out of the solar jar of saved petals into a jam jar with soda ash, confirmed that alkali deepens the dyebath from cloudy yellow to orange. Simmering the whole week's harvest with another teaspoon of soda ash made a dye bath of rich
terracotta.  After an hour simmering and an overnight soak, a skein of about 50g handspun Speckled Face Beulah woolen yarn turned terracotta orange and there was enough power left in the afterbath to dye another 20g skein a browner terracotta shade, once a slug of iron solution was added in.
Pursuing a revived interest in dyeing plant fibres, I mordanted a cotton T shirt weighing 100g with alum acetate, ready for the following week's supply of 70g yellow cosmos. The T shirt was rolled up with some sprigs of coreopsis and a few weld leaves, tied tightly with string that had been soaked in iron solution, then put into an alkaline bath of yellow cosmos to simmer for an hour or two, soak overnight and dry out.

Once unrolled, it seemed a fabulous orange.  After rinsing and a standard 30 degree machine wash with colour powder, the cotton had faded to a soft terracotta, still with deeper contact prints from the coreopsis and yellow from the weld leaves.  In future, I'll use a pH neutral detergent and a wool wash cycle.

While I was admiring this week's unmodified yellow cosmos dye result, my companion, Elinor Gotland, happened to return from another little jaunt to the Mediterranean.  Lost in thought, I jumped when she patted me on the shoulder.
"Hiya, Beaut.  Still hanging around in the garden, titting about with plants, is it?" 
"Just enjoying this big skein, dyed without any mucking about with the pH, that orange one had an alkali bath and the reddish brown had added iron. All from about one to one ratio of fresh yellow cosmos flowers to weight of wool."
"You really should get out more."  
"While you totted up air miles, I have been travelling in the realms of gold."
Elinor rolled her eyes.
"Hardly an Homeric Odyssey."
"Why don't you join me for my next epic adventure - walking the dog in the fields?"
Elinor quite enjoyed our stroll, making tableaux vivants from Keats' Ode to the golden season. She posed as 'soft-lifted by the winnowing wind', I thought 'hefty chum of the harvest mouse'. Happily, she has now developed a greater appreciation of the yellow cosmos. Never did she breathe its pure serene, Til she saw the silk scarf gleaming brown and gold. Then like stout Cortes, when with eagle eyes, He stared at the Pacific, she looked at me with a wild surmise, 
not quite Silent, on a pot plant in the garden.
"Is this a contact dye from one of your yellow cosmos baths?  Fair play, that old gold background colour on the silk may have been worth the journey."
"I like to think I've come a fair way in the last few years."
"Indeed. Take courage from that thought, Beaut.  See if you can you make it as far as the kettle without getting a nose bleed."

Plant Contact Dyes on Cotton and Linen

The horseshoe border in the middle of the back lawn gets full sun (when there is any).  Last spring, it was dug over with sheep and cow manure from my friend Mary's farm and the dye plants got promoted to centre stage.  Dangerously exposed, although the dog is one year old and considerably less destructive than she
was last summer.  In the hope of improving her garden manners, I fixed some netting for sweet peas to stop her walking straight across the earth and apart from one rosemary bush which she uprooted three times, everything else has flourished, despite another cool, damp summer. These weld plants were only sown in March, here are the rosettes in June and though they are supposed to be biennial,
several spikes were about to flower at the end of last month.  I have become somewhat disenchanted with weld and didn't bother with a late sowing last autumn.  Thrilled with the powerful yellow dye I first had from fresh plants, I've been drying and storing most of the spikes ever since.  Soaking, fermenting and simmering dried weld indoors is not altogether a welcome winter sunshine fiesta, it makes the house smell rank and at the end of it all, yellow from dried leaves is not nearly so zingy. This unexpected 250g of fresh weld ought to have dyed 500g wool, if I had such an amount all spun up and ready.  I chopped it up and left it in a bucket of cold water to ferment for a day or so, while I pondered what to dye.

Past trials of dyeing cotton and linen fabric have suggested that weight for weight, they take up muted colours, compared to wool and silk.  My one attempt at mordanting with soya milk was a big waste of time, money and beans.  The classic mordant process for plant derived fibres involves simmering in tannin, before they can take up alum like wool does. Their greater weight also means far more
dyestuff is required.  One way and another, cotton and linen have seemed more trouble than they are worth.  Being possessed of 250g powerful dye plant and a second hand, but perfectly sound linen smock also weighing 250g, rather shifted the dynamic.  Plant fibres can be mordanted in one fell swoop, using 5% of their weight in alum acetate dissolved in water.  Since the fabric is so much thicker than silk, I supposed
that dye penetration would be reduced, so once my linen smock had had the mordant rinsed off, I turned it inside out and laid sprigs of coreopsis tinctoria and hardy geranium leaves within the body, so they would be pressed against the final outside surface.  The body section was rolled around a length of plastic downpipe and tied tightly with string which had been soaked in a solution of iron.  
The sleeves were tied across a wooden board and the whole thing was immersed in my weld dyebath, which always does look deceptively weak and weedy in colour.  A teaspoon of soda ash to alkalinise the bath brings up the yellow and shouldn't make linen feel harsh, as it can with wool.  

The pot was brought up to a simmer fairly quickly, kept below the boil for an hour and left to cool overnight.  The sodden bundle took several days to get anywhere near dry in this cool, dull summer. Once unwrapped, I was thrilled to bits.  What a result.  It looked even better after a machine wash at 30 degrees and a hot iron, only I can't show you, because my friend BG has it now.

The coreopsis flowers, leaves and stems have printed sharply on the rolled linen, which was indeed dense enough to keep out most of the colour from the weld dye bath and stop the intense coreopsis from bleeding through its layers.  The hardy geranium leaves have left a blur of greenish colour and the odd dark edge. On silk, they would have left a tracery of dark iron marks, but I assume the heavy linen also kept most of the iron on the string from reaching them.  Thoroughly enthused, I topped up the alum acetate in the mordant bath, bought a linen and cotton mix shirt in a charity shop and repeated the whole process using only coreopsis and whatever weld might be left in the afterbath.  Here is how it went.

Knitting with Linen Yarn

"Look at this linen thread I bought at Wonderwool. Still perfectly good to use, even though it was probably spun in the sixties.  That's natural flax beside it. " Elinor paid me no attention.  "People have been spinning fibre from flax plants for thousands and thousands of years. Long before you sheep had woolly fleeces."  
I was keen to give my companion the benefit of my textile archeology knowledge.  "Three thousand years ago in Cambridge, there 
were Bronze Age villagers who wove linen cloth so fine it had 26 threads to the centimetre."  
At last, she turned to look at me.
"Oh, you watched that telly programme too, did you?"
Curses, I thought she'd missed seeing it. Damn BBC iPlayer.
"Yes, well, I thought I might grow my own flax next year."
"Remember your medieval nettle retting attempt, Beaut?  Or should I say, nettle rotting?"
"It was a bit smelly."
"A slimey heap of stinky stalks and not enough fibre to spin knickers for gnat." Elinor dropped the flax sample and settled her specs more firmly on her nose.  "Three and a half thousand years ago, the Mesopotamians spotted some woolly sheep among their short haired flocks. They had the sense to know when they were on to a good thing.  Do yourself a favour and benefit by that historic advance.  Wool is the way forward."

Expecting a grouchy ewe to admire my lovely new skeins of linen from Midwinter Yarns was as futile as the nettle experiment.  I found them most exciting, the plant fibres handling very differently to wool.  Though the skeins felt stiff and heavy, linen fabrics are supposed to soften with repeated washing and ought to last for years without pilling or shrinking or being eaten by moths. Of course, a sensible woman dealing with an unfamiliar yarn would have knitted samples on different sized needles, washed them and then made a considered choice about her pattern.  I just started knitting a Boo Knits Shawl called Out of Darkness.  It was advertised as 'harking back to an era of timeless elegance', so I decided using the contemporary product of a prehistoric fibre would be classically immemorial, enduring and well, spot on.
Linen is utterly inelastic, the flax fibres being smooth and straight with none of the crimp that gives wool its body and bounce.  This may be why the knitted tension in the first garter stitch section looked so uneven -  I just pressed on, hoping it would improve after a wash and blocking out.  The yarn slips along the needles very easily, which is nice til stitches accidentally slip off the needles. With little internal friction to hold
the yarn in shape for those vital seconds while you pick the lost stitches back up, lace knitting proved an exceedingly ambitious project.  I suppose plying linen has to be loose, to keep it smooth and avoid a string-like toughness.  It does mean the yarn splits easily, which would have been less of an issue if I hadn't decided on adding beads with holes only big enough to take a 0.5mm crochet hook, which often wouldn't catch hold
of all the singles at once. Knitting and beading the smallest version of the pattern took a while and once off the needles, it looked and felt more like chainmail than lace. After a machine wash at 30 degrees, the damp fabric was transformed into soft pliability, strong enough to withstand a real beasting of blocking out with pins. Elinor caught me unpinning the shawl.
"Mmm, I see it's dried stiff again."
"On the plus side, linen is holding the lace patterning to better effect than wool."
"Yes, I can see a few bodges."
"No-one will notice when it is being worn."
"Well, I shan't be modelling it."
"No need.  My daughter has no objection to plant products.  She is much more up with the times than you. Quinoa and soy milk are meat and drink to her."  
"Ooo, very impressive.  Let's ask her to eat the ragwort in the garden, shall we?"

Blending Wool Colours on Hand Carders

"This old fleece is terminally grim, Beaut.  Get over your hoarding issues and chuck the thing out." 
My companion, Elinor Gotland, was staging an intervention rather than supporting my search for inspiration and getting vexed at my disappearances under the spare bed. I called back up from beneath it.
"That's the Welsh Mountain X Dorset Down fleece I used last year for exhausting Japanese Indigo vats. Never was soft and the long soak in alkali has done it no favours.  I knew I kept it somewhere because I was sure these varied blues would be perfect for sky colours. Remember that book, Knit the Sky?"
"I remember telling you this fleece was NOT suitable for knitwear."
"Never mind how harsh the wool is, doesn't matter if you're spinning the sky as art."
Elinor kicked a heap of fleece off the duvet and jumped down, one small sheep and her forceful opinions landing on my prostrate rear end.
"Art?  My cotted rump.  Not another one of your so-called wool works.  Which lucky relative is going to have a sky blue objet de laine foisted upon them?"
I rubbed the offended part.
"Ooo, those hooves could do with a trim. Sharp as your judgements. I know my sister was really pleased to be given the Harp wool work, because it's up on the wall in her hall."
"Be honest, Beaut, it was just too big to stick on the fridge door."
I shoved a long lost pillowcase full of grey fleece in her general direction and felt gratified to hear a muffled bleat.
News of Art Challenge Wales had reinvigorated my flagging artistic morale.  Open to everyone to enter and held last Saturday, just along the coast in Porthcawl, the challenge was to create a piece of art in public on the sea front, between having your canvas stamped at 9am and handing it in to the Grand Pavilion at 5pm. Here are my sister, daughter and niece, enjoying aesthetic sustenance while better breakfasted artists 
sallied past.  My plan was to spin yarn in the colours of the sea and sky.  At 9.46am with the tide full in, I loaded grey and blue locks onto a hand carder.  OK, overloaded, I know I always put too much wool on, which makes heavy work of carding a fat rolag.  Checking the horizon for colours, I dragged away at the carders til I had eight rolags ready to spin longdraw - artistically irregular.

Because the colour changes in the rolags had spun into a single of continuously shifting hues, even Navajo chain plying often mixed shades up within one stretch of yarn. Winding the plied yarn straight from the bobbin round a driftwood stick displayed the broad effect of my colour choices, in a blurred fashion up close, better from a distance.  So, call stick number one Impressionist and try not to panic about the time, 11.15am already.  With the tide turned and the waves much further down the beach, I only made five rolags for the second length of yarn, less focussed on sea greys and more on sky blues.

The frame, which had been stamped for me when we arrived in Porthcawl, was a gnarly piece of driftwood which had already been drilled in the privacy of my own garage.  Six pairs of holes to take copper wire fixings, to be twisted through beach pebbles with holes.  I managed to shatter one stone while curling up the wires, but Pip averted crisis by nipping down to the beach to find shells with holes instead.  
Here are the first two yarns, safely in place by lunchtime.  The sun shone for much of the afternoon in a deeper and deeper blue sky. Keeping to just blue and white wool on the carders gave much crisper colour changes, accentuated even more by the stronger contrast of adding darker blue to the rolags.  The afternoon yarns looked quite different to the morning blends, effects I shall try to bear in mind next time I am carding dyed fleece to make yarn for knitting.  Guided by the falling
tide, only four, three, then two rolags' worth of yarn had to be spun, so all my six sticks were wrapped in yarn shortly after 4pm.  Handing it in at the Pavilion, I realised my thing didn't stand comparison with the proper art on canvas, but I really didn't mind, being most satsfied with my 'Driftwood Tide'.

Elinor Gotland sauntered down the headland to meet us.
"Sky Tide would have been a better name, Beaut.  At least you've got that awful fleece out of your stash - and that blue sky art foolishness out of your system."
"Oh, I'm still blue sky thinking, Elinor.  Might go Yves Klein
abstract with pure indigo next."
My companion looked around at my family, put her head in her hooves and groaned.
"That sister of yours has been encouraging you again.  She's such a bad influence."
