Clay Animation Props. Props and sets can share similar properties. A glass window can be part of a set design but can also be a prop. If a character opens the window it has now become a prop because the character has touched it. Here are examples of props that can be used to help out the look of a set. These prop pictures are actually dollhouse items that can be found at hobby and craft stores. Props are any physical items the clay characters can touch on a set. Examples include, phones, chairs, tables, pens, dishes, foods, etc. If the needed prop for a set cannot be located for purchase, the prop can always be built using clay.
