Don’t waste the demo yarn!

Whilst demonstrating as a member of a local textile group, Woolly Umbrella, at the Wild Chalk festival, I kept a drop-spindle of my own going with singles that I Andean plied at the end as part of the demo.

I don’t think repeatedly putting it down and restarting helped me get an even twist, or it may have been the plying, or a mixture of both, but the yarn isn’t balanced. I knitted a lace pattern with it, and the bias isn’t so pronounced as in stocking stitch, but I can see it.
For fun I added the knitted sample to a purple dye bath I had prepared to dye some other yarn, and here is the result.

Hand spun yarn dyed with purple acid dye.

Dyeing to be purple

For no better reason than wanted to play with acid dyes I dyed a 58g hank of handspun Texel and Clun Forest 2 ply today. Inspired by WASPI I chose to mix a purple. If we haven’t won our pension compensation by the winter I shall knit mittens for wearing on demos.

I’m going to pop 100g of Shetland fleece that has some pink staining on the tips into the exhausted bath to hopefully give it a tint.

Half-way through the tint was looking too blue, so I added 1/8th TSP magenta to bring it back towards purple.

Below is the yarn, it’s still wet so it’s going to be a lot lighter when dry.

Food colour dyeing

Today I wanted to dye some of my hand spun wool yarn a bright green. No natural dye I have would do this, and I didn’t have any green acid dye, (or any acid dyes at all), so I decided to use food colouring. I already knew that food colouring works as a fibre dye but did not realise that it was an acid dye, (thank you Google) so works best on wool, silk and other protein fibres that will dye with an acid dye. Acid dyes are not acid, but they require an acid such as vinegar or citric acid to attach themselves to the fibre.

Initially I’d intended to use liquid food dyes but discovered I have either thrown them out or someone had used them up, so had to resort to the paste colours I used to use for sugar flower modelling. These seemed to work fine and are quite intense, if a little harder to dissolve, (I had to squash some lumps against the side of the jug). I may use them again as they are just sitting in the cupboard at the moment.

So to prepare the yarn I soaked it in a mixture of one part vinegar to two parts water for about 30 minutes. This did two jobs at once, soaked the fibres to remove trapped air and added acidity. I could have added vinegar to the dyebath instead.

Meanwhile I put some water to heat on the stove and mixed the bright leafy green I wanted from my stash of food colouring dyes.

I mixed the food colouring paste with hot water in a small jug, and added a teaspoon of salt, (this helps to level the colour and increase its take-up), stirring them well until the liquid was clear, then added this to the pan of water that was warming on the stove.

When the dyebath was ready I removed the hank of wool from the vinegar and water soak, gently squeezing it to remove excess liquid, and immersed it in the dye. The temptation to stir the yarn into the dye bath is always with us, so I gently prodded it below the surface and walked away and left it. It took about 20 minutes of gentle simmering, turning the yarn very gently once, to achieve the colour I wanted.

Because I liked the colour so much I decided to dip a second hank quickly into the dyebath so I got very pale green and then, having rinse it to check the colour, I trailed half the hank into the dyebath again and let it stay in there until it became darker. This gave me a dip dyed, ombre yarn in tones of the same green.

Post-dyeing rinses brought the brightness down a little on both hanks, but overall I was pleased at how little colour came out. I rinsed quite hot; wool can take high heat and won’t felt, as long as you don’t agitate it or put it straight into cold water. The important thing is to have the rinsing water at a similar temperature to the dye bath. Wear gloves to protect your hands during these hot rinses. To save energy you can slowly decrease the temperatures through the rinses. Never let the tap run onto the wool or it is likely to felt.

Because it was a lovely day today I hung the hanks out in the garden to dry, but you can spin dry them as long as you put them inside a mesh laundry bag or a calico bag.

Both yarns were handspun with a bouclé effect. The dip dyed one took the colour less well partly because it was from a different fleece, and partly because it should really have had an additional scour before going into the vinegar soak.


Brighton Textile Art Group meeting 11th May

Well I did it, I made it along to the meeting today and joined the group. Thank you to all the kind members who made me feel so welcomed. There was a natural dyeing workshop today, but of course I had not booked in advance. However, I took some singles spun on my Spurtzler and plied this using my hands in an Andean ply. Then I had two little hanks to dye in the onion skin and the daffodil dye baths.

There is a little more detail of the day on my Natural Dyeing page.

Natural Dyeing workshop

Yesterday was a busy day, and included a two hour workshop on very basic natural dyeing. Because I wanted to make it as accessible as possible, and keep costs low, it mainly featured ‘kitchen’ dyeing.

I’d asked people to provide thier own 100% DK wool yarn, (I even suggested a yarn brand to look for as I know this one dyes really well), and prepare it in hanks. I then mordanted it over the weekend, and took it into the workshop ready to go into the dye. Unfortunately there was some confusion (well isn’t there always), and so some brought Aran, others brought 4ply and they were all different spins and types of wool, (but luckily only wool blends, not with synthetics).  I’d written out clear instructions on how to make balls into 10g hanks on the back of a chair – but even that went a bit wrong for some, so I then had to unwind and re-hank it all. At that point I began to wonder why I was doing this for free!

So now I had a kilogram of yarn soaking ready to go into an Alum mordant. Of course the more wool, the more water, and the more likelihood that you will soak the floor – which of course I did. So by the time I got it into the mordant I was not in love with the yarn!

My BIG pan was not big enough, so two lots were necessary, and the room was a bit steamy by the end of it all. I use a portable induction hob for dyeing – I think it is pretty energy efficient – and love it’s responsiveness.

So on to the workshop. Our dye materials were:

  • red cabbage
  • turmeric
  • spinach
  • avocado stones (soaked in 1:6 ammonia/water solution for a week beforehand)
  • avocado skins (half soaked in 1:6 ammonia solution for a week beforehand)
  • used coffee grounds
  • onion skins

Ammonia and vinegar were the only modifiers used to change the acidity of the dye baths, as I did not want to work with copper or iron in this situation.

Firstly a concentrated dye was made by boiling up  the chopped red cabbage, onion skins, and coffee grounds in enough water to cover them. The avocado baths were brought to a high heat, but not boiled as this helps keep the colour fresh and pinker. Once the colour was really released (this took between 30-60 minutes), these concentrates were strained into larger pots, cold water was added to make them lukewarm, and salt stirred in to help fix the colours. The red cabbage was divided into three baths: one left plain, one with ammonia added and one with vinegar added. The plain dye yields a purply-blue, ammonia encourages the dye to yield blue/green and the vinegar brings out a lilac colour. This was the fun part; the students introduced their hanks of yarn to different dye baths and they were brought back up to tempature. There were lots of ‘oohs’ and ‘ahhs’ at the lovely colours – even though I explained that they may change or wash out!

They experimented with tie-dying, dip-dyeing and rinsing and over-dye colours. Some more successful than others of course, and time (and hanks of yarn) were limited. One asked me, ‘Can I do this at home?’ , which seemed a strange question to me, but in retrospect it was a reasonable one, because it all seemed a bit to easy!
