Here is a piece of silk taffeta. I used blue tape to attach the fabric to the box so that it is suspended. First I sprayed it with some water, then I applied the paint with bits of natural sponge, and immediately spread some rock salt on the wet paint. I like how the salt affected the color.
I am using Jaquard dynaflo dye. I like the rusty orange color, which is mixed from red, golden yellow and a touch of black.
How it looked when the salt was off
This piece of taffeta was prepared the same way except that it is stretched over some padding.
