First, ink the stamp with Black Soot to completely cover the image.
Then stamp the image onto scrap paper. (You can use this image and color it in using a different technique at a later date... for this technique we will be using a second generation version of the stamped image).
You can then begin coloring in the image with the Distress markers as desired. I started with Vintage Photo for the shoes and first girl's hair.
I chose to leave the image as it is to get the feel of vintage Simplicity pattern forms, but the image can be further colored in using other distress markers, watercolor pens, or copic markers to add skin tone and other effects as desired.
Remember that these markers are water based so if you do incorporate a watercolor pen, apply watercolors lightly to avoid smudging.
