1. A process for making double-sided bulk textured material sheeting, comprising:
feeding a continuous supply of flat material sheeting to a texturing apparatus, the sheeting having first and second opposed sides; and repeatedly impacting the first side of the sheeting and the second side of the sheeting with toothed knives, each impact of each knife creating a row of raised and generally pointed structures on the sheeting, to texture both the first side and the second side of the sheeting, wherein the impacting step comprises actuating a first one of the knives generally downward and across the sheeting in a first widthwise direction, and simultaneously actuating a second one of the knives generally downward and across the sheeting in a second widthwise direction opposite the first widthwise direction.
