I went with flowers for the Friday Mashup color challenge, and I also turned to Mix-Ability Challenge #69, Faux Tile, to help me out. The main panel was created by stamping and watercoloring. For the background, I did a watercolor wash, then created the "grout" with painter's tape and sponging. I wanted to lighten up the background, so I applied a layer of gesso by pouncing. I sanded some areas of the background, once dried, and then added a layer of vellum.
