Here is my succinct rendition:
Fill the zipper freezer bag with water, soak in the fiber, squish until the fiber looks transparent. Squeeze and pour out the water. Mix the dye and vinegar, pour into the bag. Press to distribute the dye. Zip to just 1/4 inch to the end. Place in the dishwasher and run the longest and hottest cycle (no scrub) and heat dry.
I shared this idea with the Euro spinners on the French Tricofolk forum and they thought the wool would felt. So, I tried it myself using normal cycle, no pot and pan scrub. While I was able to card 100 percent of the fiber -- which meant it didn't felt -- I did have to open up the fibers at the end. Next time I will just run it on water miser just to see if there's a difference.
Here are the rovings after dyeing in the dishwasher and drying in the washing machine.
The fibers did need some opening up.
The fiber, 100 percent carded up. No felting.
Into the drumcard slicker (if you want one go talk to Heidi of The Artful Ewe)...
Unrolled...
Very nice...
Up close.
