I have been experimenting with dying fabric - this is silk chiffon which I felted after the dying process was complete. I dyed the piece of fabric using the cramb jar method and only two dye colours - a basic yellow and magenta. After dying I used wool tops to felt it using the nuno felting method (although I did not leave any unfelted fabric as is often done). This piece of fabric was completely covered on the back with wool tops for felting and as a result the front surface is totally wrinkly as in nuno.
Cramb Jar Dying method
Place some dye at the bottom of a jar, place dry fabric on top and then drop the other colour on top of the fabric, or around the sides., depending on what you are trying to achieve. Cover gently with water. I also add soda ash water before leaving overnight.
