STEP 4: Adding layered element upon layered element will give depth to your painting. Try taking a watercolor pencil and dragging it through the wet paint to create a subtle texture and mark. Be brave and try a bold mark here and there if your intuition whispers to you. When you feel the â€œclickâ€? that the work is complete (recognizing that feeling takes practice), spray it lightly with a clear varnish to preserve any delicate mark-making.
