The "tabs" on tab top curtains are the exposed loops (tabs) of fabric that you see on so many curtains. These loops are drawn through a curtain rod or pole. Long before curtain tracks and other manufactured curtain hanging systems were invented, tab top curtains were the only types of curtains available. Because of this, they remain the most popular style of curtain in country style homes. However, there use is not by any means confined to country style homes. Creative curtain designers have found innumerable ways to use them in almost every imaginable setting.
