I have a picture in my head of a richly colored flower outlined in bold black. I went to my art journal to attempt its creation. This is close, but not quite what I was after. I love the richness of Derwent Inktense Watercolor pencils, but even so they aren't rich enough for what I'm imagining. I may have to go to acrylic paints. But the bold black of Stabilo pencil, especially when brushed over with water, is going to serve just fine.
