Many deal toys involve relatively simple geometric and classic shapes; but even with standard shapes such as those shown here, a significant amount of customization will be possible. As you review the pieces in this section, keep in mind that, even with standard shapes, you can tailor a number of elements. In most cases, you will be able to add or subtract various design components, or mix and match elements you like from several pieces; and if you like the dimensions of one piece more than another, there’s no problem adjusting sizes as well.
