This chapter presents the overview of how to achieve the lovely contours and angles that may be integral to a three-dimensional finished piece. Because it is a dimensional material the edges of foam have a 'thickness'. When deliberately cutting the edges of foam at angles. These are clean, angled cuts that allow for supported, abrupt turns when hard-edged contours are needed. When two beveled edges are put together it is called a mitered joint. The term 'mitered' is commonly associated with carpentry when installing baseboards, crown molding, and picture frames. The V-shape that is created when the slash opens is called a 'dart'. Darts are commonly used to contour and curve garments to the body and other objects where fabric is used. By using the same methodology, foam can be made to curve into a bulbous, cupped shape. One good way to familiarize people with the use of darts and wedges is cutting open a beach ball.
