I have been interested in the lightfastness of natural dyes for a while. I have understood that all natural dyes are somewhat fugitive but that some are more than others. And with fugitive I mean that time and light will fade the colours. I wanted to see this with my own eyes, so I did a little experiment. Now this experiment is not the most scientific and I probably should have done it in summer time when there is actually natural light in Finland. In the end of September I collected some samples of the yarns I had dyed naturally. I covered half of the yarn stripes with cardboard and left the other half bare. The samples have been facing “the sun” (there is not a lot of sun at the moment here) on our balcony for about two months now.
And these are the results here. I’m not sure how much you will be able to tell from these photos, but basically the left side is the one that has been covered. Black beans and beet root are the ones where you can really see the difference. Lupine, birch leaves, heather, onion skins and lichen have not faded away. Surprisingly also red cabbage is pretty much the same as before after two months. I thought that it would be the first one to fade away. Other than that the results are pretty much what I expected. I’m a little sad about the fact that the colour from the black beans fades so quickly. I should probably repeat this experiment again in summer time when the conditions are more “extreme”.
In other news I knitted my first pair of woollen socks in over ten years. I discovered that knitting a heel is not like riding a bike. I think that the pattern I used is different from the way I learned to knit a heel in school (also I’m not very good at following instructions, I tend to do thing my way which is not always the right way.) I had some struggles with these socks, but I feel like I have now done all the mistakes and the next pair will be an improvement.
I used the yarn that I dyed with lupine in the beginning of the summer to knit this pair. I really like the colour and these socks are warm and cosy just in time for winter. I went for a really simple striped pattern. For my next pair I want to do something a little bit more creative, I’m thinking of some kind of fair Isle pattern and I still need to properly tackle that that bloody heel!
(I modified the pattern a little bit but the original pattern for these socks is from a Finnish sewing/knitting magazine. Suuri Käsityö Lehti Marras-joulukuu 2004)

I like your experiment. We have a very strong sun in Australia. I might do something like this in the future to test colourfastness here too. Thanks for the great idea!
That would be very interesting. You have ideal conditions for a test like this. 🙂 The last time I saw some day light was sunday morning.
My husband suggested you send a few scraps of your dyed wool over for the Australian Summer sun test 🙂
Well that would work 🙂 I kind of wish I could send myself to the Australian sun for little while.
Some how I missed your reply. I think you would like some sun. Our sun can be pretty fierce but Australia is like no other place on earth. Save up and come over 🙂
