When something is criss-crossed, it means that it is in a pattern of intersecting straight lines or paths. In this case, the straight ropes have been used to intersect each other, creating a "criss-cross" pattern. This word can also be used as a verb (to criss cross). Ex: If you criss cross these ropes, you can create a stronger, thicker rope. Ex: These strings have been criss crossed to create an intricate bracelet pattern.
