The Quiet Grove Box Breathing Calming Corner ポスター

A gentle children’s calming poster illustrating a box breathing exercise. A simple square outline divided into four equal sides, with soft arrows guiding the breathing steps: inhale, hold, exhale, hold. Subtle text near each side reads “Breathe in,” “Hold,” “Breathe out,” “Hold.” Minimalist watercolor style, muted greens and warm neutrals, soft edges, calm and uncluttered composition, lots of white space, no people, no animals, no busy background. Designed for a calming corner or therapy space, peaceful and reassuring tone.
