dyeing with buddleja

Buddleja is everywhere is Glasgow! It’s a plant that I’ve done a bit of dyeing with in Australia so I thought it was time to try it here- you never know if the results are going to be the same in another place, as so many variables can influence the production of dye pigments in a plant.

Buddleja davidii was introduced from China in the nineteenth century and, since then, has spread to all corners of Britain- the highly-dispersible seed of what was originally a garden plant has resulted in extensive buddleia populations in the wild, where the shrub often out-competes native vegetation and reduces biodiversity. Its huge number of tiny windborne seeds colonize bare ground, such as railway lines, amazingly quickly and can even germinate in decaying mortar, causing damage to buildings; many of Glasgow’s derelict buildings have been colonised by buddleja, which makes for an interesting sight when walking in the city!

It is recommended that gardeners and landscape managers remove the flower heads once the plant has done it’s lovely job of providing nectar for butterflies but before the plant sets seed in late summer/ autumn- so I took it upon myself to collect as much as I could from local streets and public spaces- free dye material!

Below is my standard process for dyeing with a new plant, followed by notes in brackets about anything specific to this dyebath:

  1. Prepare  dyestuff: Place 100% weight of goods (WOG) of plant material in a large pot and cover with boiling water (I used 500gm of fresh buddleja flowers to 250gm of yarn as I was not sure whether the high rainfall in Scotland would dilute the dye compounds and affect the amount of colour available). Soak overnight or longer for tough or woody material (I soaked for 36 hours, simply because I didn’t have time to dye before then!)
  2. Extract colour from dyestuff: Place on low-moderate heat and slowly bring the dyebath to 70C. Hold for 45 minutes. Allow the dyebath to cool and then strain out fine or soft dyestuff such as flowers or juicy leaves; you can leave large or woody materials in the bath during dyeing but, for even colour, ensure that it is not touching the yarn (I strained the bath to remove the many small florets that would otherwise get tangled in the yarn).
  3. Prepare fibres:  Place alum-mordanted fibres in a bucket of tepid water and leave to soak for at least an hour to wet the fibres through; If dyeing more than one skein in the same bath, run a long loop of string through the skeins and tie together as this will make it easier to manage them.  If your dyebath is warm or hot and your fibres are cold, place them in a bucket of warm water for 5 minutes and then into a bucket of hot water for 5 minutes to prevent shocking and felting fibres.
  4. Apply colour to fibres: Add fibres to the dyebath. Place on low-moderate heat, slowly bring the dyebath to 70C. Hold for 45-60 minutes. Remove from heat and allow to cool completely before removing the fibres.
  5. Remove fibres from dyebath and roll in a towel or spin in a salad spinner to remove excess dyebath. Rinse all other fibres in cool water until water runs clear and then dry flat. Alternatively, dry without rinsing; some dyers find that colours intensify if the rinsing process is delayed by a week or longer (I rinsed my yarns straightaway as I was keen to see the final results!).

I used a series of different fibres in the bath; from left to right above, you can see Ysolda’s Blend 1 (Merino, Polwarth and Zwartbles), two skeins of local Shetland from New Lanark, a skein of laceweight kid mohair/ silk and two skeins of alpaca/ silk/ cashmere.

Above are the two skeins of Shetland- the difference in colour between the two is due to the fact that I popped the top skein in the dye bath when I first set the dyestuff to soak so it had a long time to interact with the dye compounds, whereas the bottom one was added to the strained dyebath with the other fibres. There is a big difference in result, a reminder that some species take up colour without any heat at all and others require long periods in the dyebath to maximise uptake.

And the two fabric samples were part of an adjunct test (in which I poured boiled water over the alum-mordanted samples of silk velvet and left for 12 hours) to see whether the colour from buddleja flowers picked and used when still purple (right) yielded a different colour to those picked when already browning (left). The answer is definitely yes but, as it was getting on in the season, the material I used to dye the yarn in this post was brown… so it’s inspiring to know that next year I can get even more colour if I start picking and dyeing early enough!

Above are the New Lanark Shetland (left), Ysolda’s Blend 1 and a strand of Tarndie Polwarth. It’s always interesting to see how different fibres pick up and reflect the colour- the dark fibres in Ysolda’s yarn give it a cool cast but the strand of Tarndie Polwarth is also a little cooler than the Shetland, and I often find that dyeing with fine fibres like Polwarth and Merino results in cooler, softer colours than Shetland and other medium-strength fibres…

And these three skeins of the same alpaca/ silk and cashmere yarn were all dyed with buddleja but in slightly different ways. The skein to the left was dyed in a bath made from only the buddleja leaves, which resulted in a cooler, slightly greener shade. The skein in the middle is my control skein- it was dyed in the above-described bath. And the skein to the left was also in the above-described bath but had been previously dyed a soft buff-tan in a dye experiment fail with woad seeds- overdyeing it with buddleja resulted in a richer gold and I think that it’s interesting to see how even a very light underbase can affect the end result!

So, my conclusions?  I have some lightfastness tests on the go at the moment (it’s looking like it’s quite fast but a bit too early to be sure) and I’d like to experiment more with modifiers to see if I can get a bigger range of shades but, at this stage, Buddleja is definitely on my list of very useful dye weeds! I love the warm gold shades it yields and the fact that it is everywhere and free to harvest, that we’re actually helping the local ecosystem by harvesting the flowers… it’s such a win for everyone. And my question about whether the colours achieved here would be the same as in Australia? I think the depth of colour is not quite as intense but the shades are very similar…

And, in case you’re keen to learn more, I have one more dye workshop scheduled for the year on Sunday October 9 at the Glasgow Botanics – it should be a lovely day with some great autumn harvesting of dye plants and a day all snugged up in the Kibble Palace with warm tea and cake!

classes at handmakers factory

I’m super excited to be running some knitting and dyeing classes for the Handmakers Factory! If you’re not familiar with Nichola and Liesl and the project they are building, you can read about it here… as well as a strong focus on making clothes and other stuff to reduce industry waste and build resourcefulness, I think what is really lovely about this project is the diversity of classes on offer in one place (already, they have sewing, machine and hand knitting, dyeing, knit-a-longs and social sewing sessions) and the way that participants can then document what they make on the Handmakers site… all these things should go a long way in helping to build the community that the project is all about.

All the classes are practical and focus on building skills from the beginning up. For example, Brianna Read of Jack of Diamonds is running a series of individual classes on machine knitting, but you can also sign up for a course of 5 classes which will take you from the first step of assembling your machine (which can be more daunting than it sounds!) all the way to finishing a pair of fingerless cabled gloves. I’ve done a couple of workshops with Bri and she is a great teacher with the rare ability to stay calm in a room full of newbie machine knitters. If you have any inkling that machine knitting is for you, you should sign up for this course- I would have killed for it when I first started working on my machine!

Once Liesl has worked her magic teaching the basics of hand knitting, my Knitting Tips and Tricks class covers all the little details that enable a new knitter to move on from scarves to all the fun stuff… We’ll cover working accurate swatches, salvaging dropped stitches and fixing mistakes, choosing the right increases and decreases, picking up stitches to work button bands, joining in a new ball and weaving in ends neatly, working a 3-needle cast-off and more.

Finishing Knits follows on and covers the essential skills involved in putting together knitted garments in a professional way, including short-row shoulders, seaming, easing the pieces to fit, grafting, weaving in ends, blocking (when and how to do it), sewing on buttons and trim and more. Knitters of all levels often start to feel faint at this point of the knitting process, which is why so many garments lie unfinished for years- I thinks it’s important to learn how to break the process down into individual, manageable steps, so that you feel confident and inspired to get all those UFOs out of the cupboard!

And, just in time for the beginning of summer, I’m running a Basics of Natural Dyeing class to demonstrate the essentials of dyeing with natural materials. We’ll cover the main methods of extracting colour and how to apply it to fabric and yarn, fibre preparation and mordanting, equipment, safety and more. We’ll then look at the colour potential of our kitchen and medicine cupboards, garden and surrounding landscape, as well as sourcing more exotic dyestuffs and will work with several dyebaths from seasonally available materials. Participants get to take away small samples of yarn and fabric from the dyebath. Should be lots of fun!
