1. Why do woven fabrics stretch more on the bias, or<br />
diagonal, direction?<br />
2. State three reasons fabrics with the same weave can<br />
have different appearances.<br />
3. State two major indicators of quality in a velvet<br />
fabric.<br />
4. Which of these two fabrics would be the more<br />
costly to produce, assuming that they are identical<br />
in all other aspects (e.g., fiber content)? Explain.<br />
Fabric A: 120 × 80<br />
Fabric B: 110 × 90<br />
5. You are in a store and see two sheets for sale. Each<br />
is labeled “200 percale.” What differences in construction<br />
could there be between these two fabrics,<br />
even though both have the same identification?<br />
6. State three reasons one side of a woven fabric can<br />
be different from the other side.<br />
7. Other than by dyeing or printing, indicate three<br />
ways by which a fabric woven with the plain weave<br />
may be given added surface interest.<br />
