So, the long awaited dye has actually arrived, and I have been busy in my kitchen.
Last year I went on a yarny retreat in Lyme Regis, run and hosted by the very lovely Daisy from Devon Sun Yarns (if you need reminding, I wrote about it here) and, over that weekend, I learnt to dye yarn. I’ve had a couple more tries since then on other retreats and workshops, all under Daisy’s supervision. But I hadn’t actually done any yarn dyeing on my own, so when the idea for a temperature blanket required justification, dyeing my own colours for it seemed the way to go.
Daisy supplies excellent yarn dyeing kits (with detailed instructions for those who haven’t had the benefit of her presence) with no nasty chemicals so they are safe to use in your kitchen. But, sensing I probably needed a bit more of a challenge, and because I wanted to dye a blanket’s worth of yarn, Daisy supplied the undyed yarn and pointed me towards procian dyes.
The process for dyeing with procian dyes is exactly the same as dyeing with the dyes in Daisy’s kits, but with procian you need separate pots, pans, spoons etc as they aren’t food safe so you can’t use the pans etc in your cooking afterwards.
This type of dyeing is known as acid dyeing, which, when I first heard the term, brought to my mind memories of lab coats, goggles and bubbling beakers of hydrochloride acid and those cupboards with the big extractors in the chemistry lab at school. But we aren’t talking about scary acidic, just a bit of an gentle acidic soak for the yarn before applying the dye.
Because I was dyeing a animal fibre yarn, I made my acidic solution by adding citric acid to some water in a bucket. Luckily I had some citric acid in the cupboard, left over from some random long forgotten cooking experiment. If you don’t have any, I’d recommend you get some just for the comedy value of the faces your children will make after slyly eating some thinking it is sugar. Alas this isn’t something that is going to happen much longer as they are now learning to read and the jar has a big label so I don’t get confused (I have previously tried to make marzipan from cornflour rather than icing sugar so all my jars now have big labels). So, citric acid for animal fibre. If you wanted to dye plant fibre (like cotton), you’ll need soda ash in your soak.
I left my yarn to soak overnight but I’m suspecting that just a 30 minute soak would do it. You want to make sure the acid solution properly gets right into the fibre, so squeeze out the big air bubbles when you put your yarn into soak.
I’d already decided which colours I wanted (see the post here) so I got to mixing the dye. I decided to start with my orange, yellow and greens, because, well, you have to start somewhere. The dye comes in powder form and you just mix it with tap water adding more water or more dye, mixing until you achieve the colour you want. I made one colour at a time and put away the dye in between so as to avoid accidents (I am outrageously clumsy).
I wanted a fairly solid colour for my blanket and the obvious way to achieve this is kettle dyeing. But, despite scouring local charity shops I couldn’t get hold of an old saucepan (unless they are in mint condition, the charity shops just bin them). Ideally I’d use a maslin pan but didn’t want to use the perfectly good one I have in the cupboard as (because I am using procian) I wouldn’t be able to use it afterwards to make strawberry jam, and strawberry season will soon be upon us.
So I went with hand painting. To protect my kitchen table oilcloth I put down one of those toddler dry nites sheet things you use to save the mattress from nighttime accidents, when potty training children. Then I put down a couple of sheets of cling film, wrung out and laid on the skein of yarn, spreading it out well. Then I added my colour. I used a paint brush (the sort you use on walls) to paint on the colour and a spoon to dribble it on. It was fascinating to see how the yarn sucked up the colour leaving just a little water behind.
Then once I’d put on all the colour I wanted (and I deliberately left some parts lighter so it would look unmistakably hand dyed), I wrapped up the skein in the cling film, laid it in a glass dish and popped it in the microwave and fixed the dye by cooking it for 3 minutes, then resting for 3 minutes, then cooking again for 3 minutes. This was probably overkill but I didn’t want all my dye to run out, given it was my first time.
Once the yarn had finally cooled down (and it does come out of the microwave at approximately the same temperature as lava) I gave it a quick rinse and hung it up to dry.
It really was as simple as that. And highly addictive. I dyed four skeins the first afternoon, and another four the following morning, and will definitely do more. Now, I have to decide on whether to knit or crochet the blanket and which stitch I’m going to use…
