Last weekend my still a bit improvised studio saw another dye class. We had lots of fun with onion skins, old fustic. logwood, indigo, madder, oak bark and walnut hulls. We tried getting patterns on fabrics with iron acetate before dyeing them in another colour. I demonstrated bundle dyeing and since I don't like to open the bundles after only three days, I opened one of mine.
One of the students craved for some muddled colours after all these clear bright ones and got into an overdye binge with what was left in the dye pots. I think the basis was logwood but after some dips here and some dips there I lost track.
and another one bundled with jam lids and yarn and overdyed it several times to get this most beautiful moon and sun fabric. At least that's what I called it.I learn so much from my students, from their carefree way to just thow stuff in, bundling it up and just having fun. It sometimes seems that from the moment I set them free at the dye pots, they sprout wings and dye as if there was no tomorrow.
I tell my students to roll their freshly dyed fabrics and to let them rest for a while before washing them out properly or risking direct sun light. The rolling prevents folds at which freshly dyed cotton and linen tends to loose colour. (Though if you want it, you could just fold your freshly dyed cloth, fold it several times and set it in the sun. This way you would get a rather unique and very interesting sun shibori.)
The book is from 1959 and was reprinted several times. The fifth edition is from 2010 so I think it should be the latest. It is still full of incredible information about the production of yarns, fibres, fabrics and how to care for them. A treasure for everyone interested in textiles.
