thank you all very much, I dont know what I did to it, none of the other stuff I sculpted did this.I may repaint her.
Also thanks to whoever said she looked like a beloved doll.I know I have moved around a lot and to be so tiny and not break has been a blessing.I really like her even tho she is rough looking..lol.
I have 3 ft dolls I did out of the clay and no discoloration at all.She must have got something on her.I hope some day to want to do sculpting again.thank you all .
