1. A tufted carpet comprising:
- (a) a generally planar backing fabric having a top surface, a bottom surface and an outer perimeter;
(b) a first border comprising a first plurality of bights on the outer perimeter of the top surface of the backing fabric;
(c) a second border visually distinct from and located interior of said first border, and comprising a second plurality of bights on the outer perimeter of the top surface of the backing fabric;
(d) wherein the plurality of bights comprising at least one of said first and second borders is formed by feeding stitches of yarn in at least three distinct increments of length.

7. A tufting machine comprising:
-
(a) a feed mechanism for transporting a backing fabric having a back side and a face side from front to rear through the machine;
(b) a plurality of spaced needles aligned transversely of the machine for reciprocable movement through the back side of backing fabric;
(c) a drive mechanism in communication with said spaced needles to reciprocably move the needles through the backing fabric;
(d) a single end servo driven yarn feed mechanism for supplying yarns at selected rates to said spaced needles, said yarn feed mechanism having separate yarn feed rolls for at least a majority of the yarns supplied to the spaced needles in the tufting machine and said separate yarn feed rolls being independently operable to supply yarns of more than three different lengths for any particular stitch;
(e) a controller in communication with the yarn feed mechanism including a software control program for controlling the operation of the independently operable yarn feed rolls in accordance with a predetermined pattern; and
(f) a looper mechanism for seizing yarns off the spaced needles on the face side of the backing fabric. - View Dependent Claims (8, 9, 10, 11, 12, 13, 15, 16, 17, 18, 19, 20)

14. A tufting machine comprising:
-
(a) a feed mechanism for transporting a backing fabric having a back side and a face side from front to rear through the machine;
(b) a plurality of spaced needles aligned transversely of the machine for reciprocable movement through the back side of backing fabric;
(c) a drive mechanism in communication with said spaced needles to reciprocably move the needles through the backing fabric;
(d) a single end servo driven yarn feed mechanism for supplying yarns at selected rates to said spaced needles, said yarn feed mechanism having separate yarn feed rolls for at least a majority of the yarns supplied to the spaced needles in the tufting machine and said separate yarn feed rolls being in communication with a servo motor to supply yarns of more than three different lengths for any particular stitch;
(e) a servo motor controller in communication with the yarn feed mechanism including a software control program for controlling the operation of the independently operable yarn feed rolls in accordance with a predetermined pattern; and
(f) a looper mechanism for seizing yarns off the spaced needles on the face side of the backing fabric.
