Cover your skull with foil,
being careful to cover it completely and as smoothly as possible.
Make sure any special details such as eyes etc., are well defined.
For easier removal, fold the foil in half and then fold the folded edge over
about 1/4".
Open it back up, leaving the 1/4" ridge raised up the middle.
Using a small paintbrush, start applying the mache mixture
over a portion of the foil. Get it good and wet and then lay a torn piece
of potty paper or snot rag over the wet spot. You can press it down with your
fingers or use the dry paintbrush to make sure the paper sticks. Continue
applying the mache and paper over the top surface of your skull, over lapping
edges and avoid covering the raised ridge.
You can apply about 3 layers before you should let it dry. I put it in the
oven at about 150 degrees until it’s dry enough to handle. Flip it over
and cover the underside and let that dry.
