There are a number of ways to make a gradient yarn.
- spin one long single from two colours of fibre, blending as you go, and then n-ply it
- spin one long single from a dyed length of gradient fibre, and then n-ply it
- spin two singles using one of the above methods, and 2ply it (this could soften the blend but may also result in barber-poling)
- dye the yarn by splitting it into several small skeins and gradiating the amount of dye used on each skein (there are a number of ways this can be done)
- dye the yarn by dipping one end in one colour and the other end in another colour (this risks ending up with a quite distinct colour change)
- dye the yarn in a ball and a pan
I decided to try method 6 first.
The first thing I had to do was work out how much yarn I wanted. I plan on making some socks, so I weighed a pair of socks I own in a similar yarn. They were 60g, so I wound 60g of yarn from this massive ball of sock yarn I have.
Once I had that, I wound a smaller amount, around 15g, which I intend to use for afterthought heels. I'm not especially fond of the undyed colour of this yarn, it's a bit yellow.
Once I had my 60g, I set about finding the middle, which I did by winding a new ball until the existing one weighed 30g. Then I took that middle yarn and re-wound the ball two strands together. This is so that I will have two similar balls to work the socks from two-at-a-time.
I dug around in my "dye" box and found some nice food colours. I started with the red one. I put a good splash of red into the pan, added the yarn (including my heels bit) and warmed it up. I rolled the ball around every few minutes to try to get an even saturation.
Once it had cooled, I squeezed some of the water out and then let it dry a bit more. Since this isn't superwash, I had to be careful with it to avoid felting.
I rewound the ball in the other direction with a view to either leaving it as it was or dying from the other end in a different colour. I found that the red had split a little on the inner sections into a quite pretty shade of orange. The colour is also kind of variegated in the middle sections. I expected it would be a bit variegated, but I am surprised at how it's come out. I like it as it is though,
Next I decided to try method 4.
I hope to knit Bosc Pear (Ravelry Link) which is an asymmetric shawl/scarf. The length can be adjusted to change the size. I'm hoping to make a smallish one, so I wound off 4 lots of 25g into connected skeins.
I then got 4 plastic cups and put food colouring in them, red in one, a mixture of red and "black" in the next, "black" and red in the third, and then "black" in the fourth.
As you might know, black food colouring isn't actually black. The one I have is green-based, so I expected that the yarn will be green rather than black on that end. I expected the middle two colours to be a mixture, probably reddish-brown and greenish-brown, but it's always a bit of an experiment!
Once they had soaked for a while (overnight), I transferred the yarn into some cling film and put it in a bowl to zap in the microwave. I don't usually do this, I usually use a steamer, but the steamer is in the garage behind a lot of other boxes, so microwave it is!
As I expected, the black separated into other colours, but it's a nice progression still from the red, through burgundy, to a greenish brown, and then to a greenish grey. I think this will make an exciting scarf!
I was a little disappointed though, the cups were not really big enough for the amount of yarn, so the red is a bit patchy.
