I recommend that you produce several skulls and have a stockpile of them before you begin decorating. if you try to decorate each skull on an individual basis, you will waste countless hours if you intend on making several of these props. The best method of doing ths is to paint them like you are working on an assembly line, performing each step on all of the skulls at a single time. This will be much more efficient in the long run.

Make a wash of water and black Cat india ink or black acrylic paint. I like the ink better because it doesn’t adhere as easily, and that allows you to shift it around if an area accidently becomes too dark. Using a fan brush and the watered down ink, cover the skull completely, allowing the wash to seep into the recessed areas of the skull. By now, you will be realizing that this is a really cool project. After the skull is covered and nk has dripped all over your table, dab it from the skull, removing the big areas but leaving it in the cracks and recessed areas. Wipe off your table, and let the project sit over night.
