Since the walnut dye pot was still on the stove I pulled a couple of previously dyed fabrics from my stash to see what happened with an over dye. The blue is from an indigo vat, the print was dyed with MX dyes and the one piece is rust dyed.
I also put a piece of hot pink cotton, some cheese cloth and a piece of white cotton batting in the pot. I put them all in at the same time which was a leap of faith but probably not something I should have done. I’m not a dyer, I only play once in awhile if the occasion arises.
I think either the indigo or the rust piece still had residue from the original dye. Which ever one it was, and I suspect the indigo, saddened the dye. So instead of a nice soft brown in the white areas, I got a soft gray. You can see it in the last photos.
I think I like the rusted piece the most but there are no ugly fabrics. They all have a place in a piece that isn’t created yet.
