Since america is made out of so many different types of cultures and races, the author makes a connection with America and a quilt since both are constructed out of many different peices.
Another metaphor for a quilt would be "Life is like a Quilt".
It is effective because in a quilt the colors dont usally work together and make it look good since they are so random and different.

A great example of where a quilt would be a appropriate symbole would be any community since a lot of communities are made up of multipule different familys and/or cultures.
