Underwater hallway decor turns a long corridor into a tunnel of sea life. Blue fabric gathers across the ceiling above suspended fish and larger dark silhouettes. Paper kelp rises at the sides, while round bubble shapes and bright coral details carry the theme down toward the floor.

These school corridor decorations use the length of the passage as part of the design. Repeated blue layers pull the eye toward the far doors, and clusters of paper coral give each side its own texture and color. The empty walkway leaves space to appreciate the scale of the transformation, from the overhead canopy to the smaller handmade edges.
