The photo below shows the underpainting I did on white pima cotton.
When the underpainting was dried,I used inks to add detail.The image represents - theEdge: where sky, sun, spray and rock meet. The stitching is dense, with many threads in yellow, blue, & purple.
Below is detail. my goal was to show the sun radiating and the wet rock reflecting. You can double click on the photo to see the stitching in detail.
