Here's some examples of how metallic paint can be used in visual journals. Metallic paint covers completely and adds drama to any image. In the examples below I altered the paper with watercolor & acrylic paint and them went out in nature to draw plants from direct observation. Back in the studio I added gold metallic paint to make the plants stand out from the background. Later I used the collage technique to add in a boarder of metallic patterned paper.

In the example below I used a light wash of blue watercolor for the background and drew the plant from direct observation with a black technical pen. Back in the studio I added silver metallic paint with a paint pen. I also added some quotes using the same pen. It is always interesting to incorporate text with artwork.
