I have the horse shape, ready to attach to the background, and I need to think.
There is not enough difference between the horse and the background, and I am working on ways to make the horse important. I had thought to add black sheer silk over the horse, but that decreases its visibility even as it unifies the shape of the horse. I tried the black sheer over the background, and it darkened nicely, to exactly the same intensity as the horse. Finally I have a piece of sheer silk that is white – before I painted it black – and that decreases the intensity of the background, and makes it more subtle. If the horse gets darkened with thread during the stitching process, I might have something.
