A Tale of Woad : small scale dyeing tutorial


I planted woad in my garden a few years ago. 
It's a scruffy plant, not much to look at.


     Maybe it's my imagination,
but it seems that the leaves
already have a blueish tint.

And if you pinch a leaf, a little blue bruise appears.
needs a plant marker saying  "I AM NOT A Weed"


Woad, used in tapestries and textiles in centuries past, 
is a rare source of indigo dye that can be grown this far north.
The dye process can be (ahem) unpleasant, involving 
certain bodily fluids (or chemicals), and strange odors**
...but the color lasts for centuries!!


In the old tapestries,woad blue wool 
was often overdyed
with yellow dye (from weld plants)
to make: Green. 

As the years passed, the yellow has faded,

and some lovely ladies,
flowers,
and unicorns
have been left standing
in fields of Blue.

When I first started playing with natural dyes back in the 1990's, 
I quickly tired of tans, golds and yellows. 

I tried a recipe for 'copper penny blue'
but alas, it was not lightfast. 
Decades later, my blue yarn 
has faded completely
back to white:
crewel yarn dyed with dyers coreopsis, mullein and copper pennies

Before aniline dyes were developed, if you wanted a lightfast blue, 
you had to use imported indigo or extract the indigo from woad. 
Woad contains the same dye chemical, just at a lesser concentration.

So a few years ago, I revisited natural dyeing, 
and out of curiosity,  I grew some woad here in Maine. 
My first dyeing attempt yielded 
a still-white silk scarf, unchanged 
but for a barest whisper 
of grey-blue.  : (

The second year, I got a definite grey-blue; 
took lots of notes and 
saved seeds for another try.

Last year, following the same procedure, the blue was bluer
 but I have no idea why. 
The joy of natural dyeing!

Small Scale Dyeing with Woad:

You will need:
-first year woad plants (second year it goes to seed)
-Dyeing pots/utensils (not used for food ever again)
-RIT color remover (fresh) (craft store)
-Washing soda (the Woolery or Dharma trading)
-paper towels, paper plates, colander
-wool


1. Pick leaves. Tear them up and toss into a bowl. 
( I used leaves from 5 small plants (~8 oz) on ~2 ounces of fiber, a 4:1 ratio plant:fiber when I got grey blue; I used only 3 plants and a 2:1 ratio when I got the bluer blue! Go figure. Or maybe not. )

Pour boiling water over the leaves (just enough to cover).  Let steep as it cools for about 1 hour.


2. Strain off the cooled liquid into your dye pot. Squeeze out the leaves to get every last drop. The liquid will be a dark color, possibly a little blueish, but if it's just brown or green don't worry.

3. Cool completely to lukewarm (120 degrees F).
Stir in 1 1/2 T washing soda, enough to make the liquid turn greenish brown.
Greenish liquid on spatula. Using white utensils & containers really helps!


4. Aerate the liquid by pouring back and forth between 2 containers. I used 2 quart-sized yogurt cups.
Make sure you are getting BLUE Froth. Add more washing soda if needed.

we have Blue Froth!!
5. Pour your liquid back into the pot and reheat until just warm to the touch (~120 degrees F). Sprinkle 1 tsp Sodium Hydrosulfite (RIT color remover) over the liquid.
Avoid making any bubbles from this point on!

6. Remove pot from heat, let stand 1 hour.  Meanwhile, presoak your fiber in warm water.

7. Add fiber, gently. Let stand quietly for about 20 minutes. (no bubbles!!) The fiber will look green in the pot.

8. Time for the Magic to Happen: Remove fiber gently and lay it on a paper plate. Leave exposed to the air for at least 20 minutes. The green fiber will magically convert to BLUE as you pull it out of the pot Before Your Very Eyes!! Enjoy!

              9. Wash and rinse your fiber as usual.

You can cover your dyepot 
And keep it overnight 
for more dyeing tomorrow....
BUT 
you won't WANT to 
cuz it smells like 
**OLD CIGARS!!😝
