  • Banner material with double grommets
    Patent number: 6495238
    Abstract: The banner material is comprised of flexible polyester fabric which comes in a rolled elongated sheet. A number of grommets are placed along the top and bottom edges. The grommets along the top edge are aligned with the grommets along the bottom edge and are placed along the top and bottom edges of the banner material alternately a first distance apart and a second substantially smaller distance apart. The user of the banner can customize the length of the banner by cutting from top edge to bottom edge between the grommets, preferably between the grommets spaced the second substantially smaller distance apart in order to avoid wasting any excess banner material.
