[originaltext] Recently some researchers conducted an interesting case study

Recently some researchers conducted an interesting case study in one ethnic culture. The study was about the development of basket weaving by African-American women who lived in the town of Mount Pleasant, South Carolina. The town is known for its high quality sweet grass baskets which are woven by these women. They’ve been weaving the baskets for generations, handing down the skill from mother to daughter. Some of the baskets have been placed on permanent display at the Philadelphia Museum of Art.
    The origin of their basket weaving dates back to the 17th centuries and even earlier when these women’s ancestors came to the United States from the west coast of Africa. Now, it’s mainly a hobby. But back in the 17th and 18th centuries African and American women wove the baskets for use on the rice plantations. There were two types of baskets then: workbaskets and baskets for use in the home. The workbaskets were made out of the more delicate sweet grass. They were used for everything from fruit baskets to baby cradles.
