Dyeing roving did not work too well. I got an unsatisfactory amount of felting and did not get the color separation I wanted.
First, let me say that this is entirely my fault. I did not do any research before starting the roving dye process (though I did read the instructions before dyeing yarn with the new-to-me Jacquard dyes.)
The color I got is really nice. It looks like a blue sky with a few puffy white clouds. However, since I used Spruce green and Periwinkle blue, I was expecting something else.

(This is where the post title came from, just in case you were wondering where the goofy titles arise.)
Procedure-wise. I measured out some roving (13 arm-lengths is a pound, so I used about 3-ish). I braided it so it would not “float apart”. I soaked this in luke-warm acidulated water in a 3-gallon zip-top bag (with the zipper torn off because those bags are poorly manufactured).
I added a quarter-cup of boiling water to each dye pot (the 1/2 ounce jars) to make a liquid dye. This is recommended by the manufacturer. Then I put a straw-full of dye liquid on one side of the roving braid in the bag full of acid-water. I used another straw to add another dye on the other side. There was very little uptake of dye.
Eventually I drained out most of the dye water from the bag and put the bag of wet roving in the steaming pot.
There are several points at which I believe I erred.
- braiding the roving. This is a stupid idea. If the roving is going to come apart, dead nylon hose would have been a better choice to hold it together.
- I did not use soap. Soap increases dye uptake and reduces white spots.
- I smooshed the fiber around way too much.
- not using a drinking straw for the second color of dye (turns out that “straw” was blocked up)
- I used too much citric acid powder
I did pull the drying roving into vertical strips and it will be spinnable, though not effortless like some of the professionally dyed rovings have been. Of course even the professionally dyed rovings have had chewy sections.
My current plan, after having read all sorts of advice from other people’s blogs and websites, is to work outside, tape newspapers down, add a plastic tarp, spread plastic wrap into a long length for each roving. Additionally I plan to pre-dissolve the acid powder in hot water and to pre-soak the roving in cold water (which has had the acid and some soap mixed in). Then I will drain the soaking water off, lay the roving out along the plastic wrap, and paint the dyes on. This painted roving will sit out in the sun. When it is dry or mostly dry, I will carefully wrap it in plastic wrap and steam it. When that is cool, I will rinse it and rinse it again.
