In this experiment I have again spent time altering both the opacity of the marks, as well as the ordering of the layers I'm working on. Each different coloured mark is placed on a separate layer.
In my previous work where I was painting with fabric dyes, I always had difficulty using white pigments as they would dry to a chalky finish. Also unlike oils or acrylics, once you had placed a darker tone onto the canvas there was no viable way of laying a white mark back over the top.
Here I am enjoying the freedom to use white to sit on top of darker hues.
