The carpet is also specially woven with 13" wide stripes where the yarn on one stripe is wound clockwise and the yarn on the adjecent stripe is wound counterclockwise. These stripes are divided by a half inch wide stripe where the yarn is slightly shorter than the rest of the carpet. This gives an effect similar to that caused by use of a vacuum cleaner.

As a result the carpet always appears to have been freshly vacuumed, even when the only housework performed in the past few months is a quick gathering of moldy pizza boxes and mostly empty beer bottles followed by a through spray of air freshener.
