Claim:
1. A method of forming patterned tufted articles, comprising: moving a backing through a tufting zone; reciprocating a first and a second series of needles into the backing so as to present a series of yarns carried thereby at different penetration depths; as the needles penetrate the backing and present the series of yarns carried thereby to each stitch area, engaging the first series of needles with a first series of gauge parts and engaging the second series of needles with a second series of gauge parts so as to form tufts of yarn in the backing of different pile heights; shifting the first series of needles to an off-gauge position; and controlling feeding of the yarns to the needles of the first series of needles to selectively pull back at least a portion of the yarns carried thereby.
