Above a Bed
Place the main whale, turtle, or ocean scene above the headboard.
Keep small removable pieces away from areas that are frequently touched.
Around Shelves
Use fish, bubbles, or sea plants beside shelves rather than behind them.
Keep books, labels, and storage items accessible.
Near Windows
Place animals beside the window frame instead of across curtains and trim.
Consider how sunlight may affect the wall and decal over time.
Above Toy Storage
Keep the main characters above the tallest bins and toys.
Use lower sea plants only where they will remain visible.
Create Movement
Arrange fish and bubbles in a loose directional path.
Avoid placing every animal in a straight line.
Balance the Wall
A large whale on one side can be balanced with smaller fish and plants on the other.
Do not force perfect symmetry.
Conclusion
Arrange ocean decals after furniture is placed. Keep main animals visible, preserve shelf and window access, and use bubbles and fish to create gentle movement across the wall.
