I’ve written about some of these already, but don’t they look lovely all folded together in a box?

This is all of the fabric I’ve dyed in March and April, not including that from the perpetual dyebath, which is still waiting to be washed.

From left to right:

A few olive greens and pale greens (they look kind of whitish here) from exhaust baths of pomegranate and turmeric with iron. Adding iron to the used dyebath initially shifted it to murky olive greens, and dyeing in the exhaust from this produced soft, pale springy greens.

Cutch (reddish) and cutch + iron (olive-brown, a bit purpley looking here).

A few pieces of cotton printed with rusty metal, using the vinegar-salt-oxalic acid method and left bundled in a basin for a few days.

Indigo, loads and loads of indigo. This is about half of the indigo fabric I’ve made recently; the rest of it is still waiting to be neutralised and washed.

Everything to the right of the indigo is pomegranate and turmeric: a straight 50/50 mix for the yellow, then a series of reheating the exhaust with iron to produce swampy dark olives, acidic lighter yellowy olives, and some lighter soft greens. There’s a mix of cottons and linens here, all reclaimed fabrics, destined either for clothes or quilts, and a stack of (new) cotton bandannas over at the right of the frame, which I’ll probably piece together into a dress.

Recent experiments in the dye studio!

This is a cutch dyebath I recently made with Lisa of asil (link: asil.ca). We split the dye into two vats and added iron to one of them hoping for a good range of browns. The result from the straight cutch was predictable, a range of reddish brick tones (seen on cotton and linen in the above photo). The iron vat didn’t give the same warm chocolatey brown shade I achieved last year, when I dyed a piece of linen to make my partner some brown pants. Instead we got this almost charcoal gray brown drab, the result of going too heavy on the iron. I’m pretty much a master at this point of going too heavy on the iron, if this kind of clumsiness were the sort of thing over which one could claim mastery. You can see the too-iron-rich brown on both cotton and linen above.

I’ve been having lots of success with this brew lately, and have finally hit upon an easy and abundant source of the swampy olive tones I so crave. This is a 50/50 vat of ground pomegranate skins and turmeric. I read about adding pomegranate to turmeric to improve its lightfastness in the guide to natural dyes published by Maiwa, a great resource and the place where Lisa and I buy a lot of our dyes (link: MAIWA). They didn’t mention proportions so half and half is what I’m trying. This vat just keeps on giving, exhaust after exhaust, and the colour is just WOW.

After the first load of glorious gold fabric came out, I reheated the exhaust dye and threw in this collection of cotton yarns, which all started out either white or very pale gray and had been gunked up with a myrobalan tannin in the mordanting process and a dip in iron water to produce dirty gray tones.

As I had hoped, the iron present in the yarns permeated the dye vat and shifted the whole thing to a murky olive green.

The resulting yarns, due to the variations in their iron content, came out a lovely range of the swampiest greens I’ve yet achieved. Here you can see them drying along with a set of the same yarns, pre-dirtied in the same manner and then dyed with indigo. This will probably be the bulk of my summer knitting as there’s enough yarn here for three warm weather sweaters.

After the yarn came out of the dyebath it looked like there was still a fair amount of colour, so I heated it up again (exhaust #2 now) and dyed another load of fabric. Here are the resulting fabrics together in the rack:

And the fabrics after drying, but before their final wash (which I try to put off for a couple of weeks if I’m not in too huge a rush to sew something). From the top, with iron on cotton, on handkerchief weight linen that had previously been dyed very lightly with madder root (red), two pieces of secondhand linen duvet cover that started out oatmeal colour, and the unadulterated turmeric-pomegranate gold on the same duvet linen, and on cotton bedsheet.

I’ve since done a second round of this same dye bath and managed to get loads and loads of weird acid greens and paler sludgy olives. Pictures soon!

I decided to give over one of my dye pots to seeing what happens if a dye is kept going and added to over time. I started with a little pile of leftover dyestuffs, 100g each of coreopsis flowers from the garden, osage chips, sappanwood chips, buckthorn, and eupatorium, that I had used to make extracts for printing pastes. Cooking up those leftovers yielded a lovely soft orange.

Here’s some wool roving, linen, and cotton simmering in the vat.

Here’s that wool roving overdyed with indigo; the deep orange spots are where the cheesecloth bag of coreopsis was nestled up against it.

On the second day I added a teaspoon of lac extract. It made the orange deeper but left tiny red dots of undissolved dye everywhere.

Enjoy this camera reflection in a reddish vat.

On the third day I added some henna powder and a cheesecloth bag of dried, shredded eucalyptus leaves along with a bit of spent logwood dyebath to top up the liquid. I don’t recommend combining henna and eucalyptus unless you like your studio to smell foul for days. But it shifted the dye back to a nice light orange.

Here’s a photo of the 3rd day fabric in the drying rack. I treated half the fabric in 2% WOF ferrous sulfate and shifted it to that dull olive below, which got me so excited I dumped the rest of the ferrous solution into the dye vat and stripped my dress off and tossed that in too. The dress didn’t get dark enough and had to be dyed one more time, and now my perpetual dyebath is tainted with iron. Whoopsie!

Here’s that 4th iteration of the vat with the iron added and the dress and other fabric simmering.

And here’s the fabric from the first four days. From top: the original orange; orange deepened with lac extract and tiny red spots of undissolved lac (not sure until it’s been washed out whether those spots are permanent); a different orange from a smellier vat; smelly orange dipped in 2% ferrous sulfate; olive drab from ferrous added to the vat.

Now this vat will be for mucking up and saddening too-bright colours, until enough of the iron is exhausted that I can start shifting the vat back to happier colours.
