I have redyed my walnut cloth results. The green was just ugly. A special thanks to Joanne Harper. She suggested using an iron pot. I had an old rusty one that I keep my rust dyeing objects in. I poured the cold walnut dye, husks and all in to the iron pot. Then I put my pole wrapped piece in. I was planning on leaving it several days but I had to look this afternoon and it was all ready a lovely chocolate color.
I removed the pole wrap and put the new fabric in. Instantly they began to turn various shades of brown. The fleece (or batting?) fabric became a very rich black. But alas it will not work. i pulled the other batting piece out from Thursday and photographed it. Then I squeezed the water out and it was just a very light gray.
Fabric two was unbleached muslin - pole wrapped, before and after rinsing.
