After seeing the Marvy Metallic Markers on the gloss tag, I wondered how it would work with Acrylic paint on canvas. I had a small canvas already painted with a back ground and added the Marvys on top. I like what happened, but it took a lot longer for it to dry.
After it dried, I used embossing powders to add another layer. I am still thinking about going back with either more ink or paint to add strengthen a focal point.
