I am teaching a class next week and needed to dye some more silk for embellishment.
I had looked in my silk box to see what I had and I seem to have a lot of green and not much pink/purple.
I use a variation on the scrunch dying I use for the scarf blanks. I soak the silk in a little soapy water to get them properly wet before dying. 
I use just enough fibre reactive dye to cover the silk. Then leave it for about an hour and put the PH up (sodium carbonate) in. I mix the PH up one tablespoon for each cup of water including the water I am mixing it in. Then I let it sit for a few hours.
One of the colours I wanted was a nice brown but when I rinsed it all the brown stayed in the water and I had purple. I haven’t had that happen before.
This is what they look like after rinsing and squeezing all the water out, they look a mess.
After they are dry, they fluff up some, but still not very nice looking
Next, you shake them out a bit and give them a tug along their length. Now they are pretty. again. Now I have a good variety for my students to choose from. The top one is the one that should have been brown. 
I think I am just about ready for the class. Just some plastic to cut and pack it all up.
