Not that I actually have a dye house, I use my kitchen. Which immediately limits colour possibilities as I refuse to work with anything more toxic than alum in a space where food is prepared. But never fear, I still have plenty of scope for experimentation. And for accidents and emergencies!
Harmful substances - arsenic and mercury among them - were once essential ingredients in the colouring of textiles, and so were smelly ones like stale urine. In fact in times past Jewish wives could sue for divorce if they found the stench of their dyer husband's work unbearable. Mr K. has declared himself to be not too keen on the smell of boiling dandelions, although I don't think he's planning on leaving me just yet! I
was hoping he might agree to start peeing in a bucket of a morning - oh yes my lovelies, your fella's urine is absolutely essential to the proper processing of your woad - but maybe I should rethink that!?*
I did give him a fright the other day. I was processing some mouldy lichen I'd 'rescued' from a fallen tree the council were about to chip - lichen makes the most fabulous dye stuff but is so slow growing that it really shouldn't be removed from its natural environment unless it's about to meet a sticky end - and I was wearing a facemask I'd borrowed that was meant for folk working with asbestos but which was usefully preventing me from inhaling any fungal spores. Apparently it gave the impression, when he walked in unawares, that there'd been a bio incident locally!
And I gave
myself a fright yesterday, when I bungled things with a pan of hot dye and got a steam scald for my trouble. I swore, a lot, and now have a truly humongous blister on the inside of my wrist, and a much larger area of my inner arm that's just very red and sore**,
and a great swathe of bandage that looks like overkill but which the lovely nurse at the GP's surgery, who I popped up to see this morning, insisted was necessary. It doesn't seem like five minutes since she was administering a tetanus shot after I gashed myself on a broken piece of old farm gate I'd intended to use for rust dyeing. I'll be getting a reputation for recklessness if I'm not careful, or maybe lunacy!

You might want to skip this bit and jump to the footnotes if you're unlikely to be trying a spot of natural dyeing any time soon, but if you fancy boiling up some dandelions, or daffodils, or dahlias of your own, read on, I have some safety tips for you. Although given recent events you'd be forgiven for double checking them elsewhere
First up, remember natural is not synonymous with safe. Some dye plants are also food stuffs, dandelions and tea leaves included, but others, such as daffodils, are toxic in some way. Indigo is a skin irritant, for example, and so is the sap of cow parsley, and logwood contains toxins that can be inhaled, absorbed through the skin or ingested. Take care. And remember that the adverse effect of many poisons is cumulative over time. (As an aside, natural is also not synonymous with eco-friendly. In fact unless you're picking wild plants or plants you've grown yourself it's quite probable that somewhere between seed and harvest a pesticide, herbicide, or some other 'handle with care' substance got in on the act.)
Set aside dedicated pots, pans and utensils for your dyeing experiments and don't use them again for food.
Store chemical mordants safely away from children. Less than a teaspoon of dyer's alum (aluminium potassium sulphate) could be fatal if ingested by a small child.
Avoid working with plant dyes in your kitchen unless you're confident you're using nothing toxic.
Make sure that wherever you do your mordanting and dyeing is well ventilated.
Use rubber gloves, wear a protective apron, and wear closed shoes in case hot liquids spill.
Wear a suitable face mask when working with fine powders or mouldy plant material.
Don't eat or drink while you're working with mordants and plant dyes.
Carefully dispose of used mordant and dye solutions down external drains or by pouring onto waste ground.
And if you can handle all of that, have fun!

* Okay, so I wasn't really, but I've had great fun teasing him about it.
** Should anyone be wondering, that's in spite of running cold water over it for a full half hour, using cooling gel, and encasing it in cling film. Honestly, the things we find ourselves doing for our art!

And finally, thank you m'dears for all your thoughts on the merits of Pimms and pink knitwear. I'm not sure I mention often enough how grateful I am for your continued interest in
knitsofacto and the conversations we have here, so in case I don't, I just did!
