Waviness and rippling occurs both around the seams and along the side. The tension put on the fabric by the powerful spring-loaded folding arms causes the areas where there are double thicknesses of material (seam, side hems) to press down harder on each other resulting in waviness and rippling immediately adjacent to the seams/side hems.
This particular natural characteristic is more noticeable on plain (solid) coloured awnings fabrics with mid-dark fabrics including warm reds, royal blues, forest greens etc the most noticeable. Striped awning fabrics tend not to highlight this characteristic as much due to the varied colors of the stripes which ‘hide’ to a degree the waviness or rippling that occurs on awnings fabrics.
