Colour run stain on embroidered Kazakh wall hanging
We bought a beautiful wall hanging while travelling in Central Asia. It has coloured embroidery on a black fabric background. The wall-hanging got a bit wet and the black colour of the background fabric ran into the coloured embroidery in a small area. I do not want to wash the whole thing as I am worried that the black of the background fabric will run again, so I think I need to remove the black dye from the embroidery by carefully dabbing it with some kind of liquid that does not need to be rinsed out - Do you have any advice?
Many thanks, Anna
