Bill of Materials
Main Components
There are only about 4 different types of cloth used in the suitcase, but they make up approximately 200 components. Some of these scraps of cloth are only a square inch or two, while others are as large as 5 or 6 square feet. Since there are only a few different types of cloth, each cloth has been given a name and components are listed with the type of cloth used and the size of cloth used. The suitcase also only has 6 different types of seams where these pieces of cloth are sown together. Examples of each are shown below the bill of materials. For simplicity, most of the individual pieces of cloth have been omitted.
