This problem will disappears completely after some time open " taking sun ".
The manufacturing of awning crystal is in two ways:
Less numbers of welds, however can have shrink in width after some weeks, because product doesn't possess internal plot. Due to static energy generated by attrition in rolling up and extremely flat surface, awning Crystal " glues " if it is coiled for several hours.
