This post is for Sarah, who’s very kindly been saving her leftovers! Paul and I don’t eat onions (weirdly, they burn Paul’s mouth – does anyone else have this?), so Sarah’s been hanging on to her onion skins for me. This looked like a lot, but only weighed about 6g, so I only added small pieces of fabric that added up to about 8g. Judging by the colour of the dye bath, I could have added a lot more!
As with my previous experiments, I simmered the onion skins in almost-boiling water for about an hour, before removing them and adding the wet fabric. I left the fabric simmering for another hour, then switched off the heat and left the saucepan to cool.
Once again, I didn’t use any kind of mordant for this experiment. The colour of the water led me to hope for some really bright fabrics, but the actual results are a lot more muted. I’m definitely going to need to add mordants to my experiments if I want to explore the full potential of the colours available from plants.
Silk dupion, silk paj, silk noil, bamboo, cotton muslin
This time the dye came out rather patchy, and with very marked differences between the fabrics. The silks have once again taken up the colour much better than the vegetable fibres. The bamboo in particular is very pale, especially in contrast to the silk paj!
The next part of this experiment is to keep some of the fabric pieces I’ve dyed so far closed away in a book, and leave others to hang in a window. That will help me to find out how fade-resistant they are. (I suspect not at all.)
Sarah also gave me a big pot full of previously-cooked blackcurrant pulp, which is very exciting! I had intended to try solar dyeing with it, but I don’t think the sun’s come out once today. Maybe at the weekend, when it’s forecast to perk up a little! Failing that it’s back to the big cooking pot, in the hope of coming out with a lovely shade of blue.
