IT being the styling of contemporary dolls and their fashions to look vintage with a bit of grunge similar to the look of a Charles Dickens' character: the orphan or the street urchin.
In the previous post AM was attempting a coffee dye to several of her doll's fashions.
Several prims live in Drearydom with skins and surfaces that have undergong this "treatment."
From Old World Primitives on Etsy - a short introduction:
"Primitive folk art dolls get their aged, antiqued look by tea staining or coffee dying the fabric they are made with. I prefer to work with undyed muslin fabric when making primitive dolls because it already has a bit of a primitive texture and color to it, and it absorbs the tea or coffee nicely. The muslin can either be dyed before or after you start making the doll. I find that doing my dying after the doll has already been constructed is easier, so that is the method I am doing to describe."
