Artificial turf system

An artificial turf system for installation over a receiving surface, the artificial turf system comprising:

• a sheet member made of a flexible material, the sheet member defining a first surface for interfacing with the receiving surface and a second surface;
• primary yarns made of straight fibers backstitched in and threaded through the sheet member and upwardly extending from the second surface of the sheet member to a first elevation;
• and
• secondary yarns made of textured fibers backstitched in and threaded through the sheet member and upwardly extending from the second surface of the sheet member at a second elevation less than the first elevation defining a difference in elevation which is caused by a difference in texture between the primary yarns and the secondary yarns, wherein the secondary yarns are more rigid than the primary yarns, and wherein the primary yarns and the secondary yarns have ends which are cut after being threaded through the sheet member.
