Well, first you start by putting a bottle on your work table. Then, without touching the bottle, you carve the shape of the bottle and then sand it. After you sand it and, again, without touching the bottle, you use some asphaltum, burnt umber and black to get the right shade of the bottle. Then ( don’t touch the bottle ), you use a light beige to create the label and outline it in gold. And then, with a soft HB pencil, you draw in the label script. Apply a bit of satin urethane on the painted label and paint the rest of the bottle with 30 minute epoxy to give it a nice gloss.
Now you can have a swig from the bottle.
