To mentally prepare for the impending act of artistic creativity, I poured myself a gin and tonic, and drank it in a single gulp.  Then, aware of the heavy responsibility I was undertaking, I made another. 

Next, I painted a picture of Jesus on the tortilla, using my browning/paint mix.  I used cheap, stiff bristle brushes that are designed for use with acrylic paints.  I save money on brushes so I can buy more Tanqueray.

I used an opage projector to project a picture of Jesus onto the tortilla, then painted the darkest areas - the hair and beard, the eyes, the nostrils, and so forth.  I didn't bother shading too much, I just got the dark areas defined.  Shading comes later, when I will actually burn the tortilla.
