Dyeing to try something different

While my sister Jenny was here in August she knitted some hats for me.  Two were knitted in a possum/merino blend which was a taupey brown colour and the other used an alpaca yarn in a kind of dirty looking, washed out pale aqua blue.  Back in New Zealand Jenny had been experimenting with dyeing the possum yarn with food colouring, so we decided to try a little bit of dyeing while she was here. 

  Possum/merino hat soaking in citric acid and water mixture

Basically the wool yarn (or garment) is soaked in an acid solution for about an hour, then a dye solution of water, food colouring and vinegar is made, the yarn is added to it and gently agitated in the dye solution, then heated.  (We used a microwave to heat the dye solution but it is possible to do the heating on a hotplate.)  Once the dye has been taken up the yarn is then left to cool in the dye solution for 30 minutes or so then the wool can be gently rinsed until the water runs clear, spun in the washing machine to get out all the water then dried flat.

one of the hats after the dyeing has almost finished,

This hat was knitted in alpaca and was originally the same colour as the knitted garment underneath

We had already dyed one possum hat with red food colouring (the left hand side)  but it came out quite blotchy, the one on the right was dyed with rose pink food colouring, it has some faint blotches as well. (The photos aren't quite true to colour possibly because the photos were taken outside and I think the colour is a bit washed out.)  The original possum/merino blend is underneath and is in reality a wee bit darker than the photo shows (the photo of the hat soaking in the acid mix is closer to the true colour)

Jenny mentioned that it is easier to dye skeins of yarn and if there is a bit of blotching then it is less noticeable once a garment has been knitted.  The aqua blue hat had very few blotches, we're not sure if this is because it was a different yarn (alpaca) or because we used a larger container for the dyeing which meant that the hat had a bit more space to move around in the container. 

The dyeing procedure doesn't take too long and it was a fun way to spend an hour or so on a gloomy, rainy winter day.


  1. Aren't you clever Pip?! I would never think to do this! The blue hat is lovely!

  2. Wow, that is gorgeous, I haven't done a lot of dyeing, I think I'd make too much mess! But yours turned out so nicely, I may need to have a go one day! xx

  3. Oh my goodness Pip, what a fabulous idea. I never would have thought of dyeing with food colouring! The colours are just so nice, and I especially love the blue. And your knitting is so beautiful too!

  4. Gorgeous colours with your dyeing. Wouldn't mind the hat pattern?

  5. Wow, love this idea. I have often thought of dyeing, but it seems expensive to buy a package of dye, when all I want is a small amount. And the blotchy-looking hat looks fabulous. When it is too uniform, it looks factory made. This has character.

    1. I think dyeing with food colouring is much cheaper, I plan to do a little tutorial on the dyeing process sometime soon.
