You guessed it...another Flourishes stamp. I sure hope this is CAS enough. I stamped the image in memento black and colored it with a combination of Copics and Prisma pencils. I cut the shape with my new nestabilities wonky rectangles (and I tried to used the tutorial, but for this shape, it just wouldn't work!). I matted the stamped image with a dark blue and adhered the white to the blue with four "screw" brads. I also drew a line behind the mug to help ground it.
