DescriptionA closeup showing the difference between Bore Worm and Reinforced Inverted Round.
The Bore Worm samples (on the left) offer a perfect symmetry of grain with six different ridges, evenly spaced.
The RIR samples (right) have a more triangular cross section. The distinction between these two weaves is most visually apparent where only one "captive" ring is used per cell.
