[step] For a brain with a diameter of 4 inches (10 cm), each ball of clay you pinch off should be about 2 inches (5 cm) in diameter. This brain will only be one color.

Ending1: Use a sharp pair of scissors to carefully snip away off equal parts of clay as well. For example, if you have a bite size snowman, or you have 3 big balls of clay, then use 4 small balls of clay the same size. Ending2: When working on a large brain, it's best to use clay or clay products with a much narrower diameter. [substeps] Find clay solid colors that show up on the clay. Ending3: Before you move on to its other color, you need to thoroughly dry each ball of clay so it is dry. [substeps] Pinch off one ball for every inch (2.5 cm) clay you pinch off; this will give you the most accurate results. Ending4: Choose a pale pink or gray clay for best results. [substeps] Each ball of clay you pinch off during this step will need to be about half the desired size of your final brain.
