I've been dyeing some samples with a view to designing a silk scarf one day.
This is following instructions in Ann Milner's Ashford book of dyeing. There are 36 one gram lengths of silk noil yarn. The dye is from Kemtex, procion MX.
It did not go entirely without problems, one of which you can see in the photo. Sample number one, in the top left corner used a 0.1 % solution instead of a 0.01% solution. And I would have expected some browns in the middle section and less of a sudden change from green to purple.
But it is my first attempt, and it was not an absolute failure. I can see some good colours amongst the horrid!
