Acid for acid exhaust dyes! Who would have thought… In a previous attempt at dyeing, I forgot to add vinegar and the result was murky, slightly felted roving. Ugh. So this time, I soaked the Polworth roving in cold water plus a big glug of vinegar. The result? Juicy colours. Yummy.
I used a slightly different process this time too. Just before the trip, I bought an 18 qt. Turkey Roaster for cheap at Walmart. I didn’t like how the dyes would sink to the bottom of the Crockpot and make a big muddy mess of the roving, so I used the cold-pour/saran wrap method as shown in the Twisted Sisters book. This gives so much more control over where colours go (and stay!).
I broke off 7 lengths of roving, each 30g, and “painted” stripes using the 0.5% dye stocks I had already made up. Wrapped them in saran wrap lengthwise and then coiled them up. Placed them all in the roaster and steamed them for about an hour — I know 20 minutes is enough, but I put them in a cold roaster and heated the whole thing up so that I wouldn’t have to transport potentially leaking coils from the dining table to the kitchen counter…

Roasted Rovings with Melted Saran Wrap in Washfast Acid Broth
In the Twisted Sisters book they have a photo where the roving packets are “all puffed up” so that you know they are done. In my case, the crappy saran wrap I used melted onto the rovings. Woo hoo. But it was no problem. Plastic and wool don’t mix so I just ripped the melted saran wrap off and the roving was still safe and intact. Just in case, I bought some thicker, heavier-duty saran wrap for next time!
Here are the lovely colours I got:
Yay, exhausted dyes means great colour.
After a day of drying, I pre-drafted the whole lot. Just gently attenuating the rovings until fluffy. See pre-pre-drafted and pre-drafted shots here:

And here’s the whole 210-220g lot of dyed Polworth roving! Happily, none of it’s felted and it’s still soft. So pretty just like that, I’ll have to decide how to spin it up!

Next time, I think I should pull back a little and try some more “subtle” colourways! These colours are gorgeous…but blinding, non?
