My response to the Journal52 Prompt, Grid-inspired, is a mixed media that started life as a pencil-drawing of leaves; done as a teaching exercise.
I erased most of the pencil drawing, just leaving a light impression. Then I added water-soluble Distress Markers, laying down Spiced Marmalade, Rusty Hinge, and Walnut
Stain more or less at random, but leaving the light center uncolored.. A water-brush was used to blend it all. Once the paper was dry, I did the tangle patterns with Ohto Graphic Liners, size .03, .01, and .005.
Golden's Titanium white acrylic paint worked for the highlights. Some of the highlights, I dabbed immediately so they just barely lightened. Once dry, I touched the water brush to the Spiced Marmalade Distress Marker, picking up just enough color to tint the smudged highlights.
This mixed media was done in a Stillman & Birn Delta sketchbook.
