I spent a happy (ha ha) half hour picking nettles last week, and another not-so-painful time collecting laurel leaves. These were going to be my latest experiments in natural dyeing. Yes, I know everyone else has probably moved onto far more exotic materials, but I am still plodding along with what I remember to collect in the park or garden. Luckily I had a pair of gloves (it was windy and cold), and a clean dog poo-bag in which to store those nasty nettles. I didn’t think the nettles would sting through gloves, but they seemed to. My fingers were still stinging when I went to bed.
So I chopped up the nettles and laurel and boiled them in large pans, left them to steep in the cooling water and re-boiled the next day, left them to steep again.
So far the liquid was looking a pretty good colour. Next I strained this off and pressed the remaining soggy leaves to remove all that precious colour. To encourage the dye bath the give up all its colour, I added some salt to the dye bath.
I had already mordanted hanks of DK wool, and some of Aran 60/40 wool acrylic in a pale tweedy beige to see what happened with this coloured blend. The mordant was 8% Alum with a teaspoon of cream of tartar added to the water. This was also boiled for an hour and left in the mordant overnight before being rinsed and used damp.
The damp hanks went into the dye baths, and simmered away for an hour or so, then I removed those and added some vinegar to the laurel bath and added some new hanks. This was supposed to make the colour a little pinker, but not sure it did.
The nettle hanks were put into a bowl of copper modifier to see if the green would intensify. It did.
Because I wanted to check out the colour saturation possible with the 60/40 blend, I had included a hank of this with each test.
Next I made a madder bath (cheating here with madder extract), and dyed two hanks – keeping the heat below boiling to try to preserve the brighter red. Not sure I managed this, but got some lovely rich reds.
Finally I made an onion skin bath and dyed a hand of 60/40 wool acrylic – bingo, this worked really well!
Above hanks left to right are: laurel (DK wool), Laurel (60/40), laurel +vinegar (DK wool), madder (60/40), madder (DK wool), nettle+copper modifier (DK wool), rather obscured hank is nettle (DK 50/50 wool acrylic – this slipped through when I was mordanting), nettle +vinegar (60/40), and at the top, onion skins (60/40).
And below are the small hanks wound into knitable balls.
On the left is a hank of hand spun yarn that I dyed the week before last using oyster mushrooms gathered from a tree trunk.
I dyed a couple of hanks with mushrooms, not an exciting colour, but very pretty.

So that is that for the moment, but I am pleased with the results, and will be sharing them with students before a natural dye workshop next week. There won’t be time to stew up plants as I did for these, but we will be using red cabbage, carrots, madder extract, onion skins and turmeric with vinegar as a modifier. Plus we will be over-dying, dip dying and tie-dying for effects.
Should be fun!
