Chinese New Year Calligraphy
Title: Chinese Calligraphy in the Park 🖌️🍃 (Beginner-Friendly)
Description:
Join us for a calm, aesthetic outdoor session of Chinese calligraphy in the park — a slow, mindful practice where nature becomes your studio.
We’ll begin with a short story: how Chinese characters were inspired by observing nature, and why in calligraphy the most important thing isn’t speed, but attention.
Then we’ll practice step by step:
• Brush basics: how to hold the brush, where to press, where to stay light
• Water practice: strokes on water-writing sheets (they appear, then fade — no fear of mistakes)
• Ink practice: training sheets with ink for deeper, more confident movement
• Final piece: your chosen character on rice paper
(Optional: add a fingerprint stamp as a personal mark of the moment)
You’ll leave with your finished calligraphy — a small art object and a memory of a quiet, beautiful morning.
What to bring:
Comfortable clothes, a bottle of water, and a curious mind.
All calligraphy materials are provided (brush, ink, water sheets, paper).
Level:
Open to beginners — no experience needed.
Meeting point:
📍 Parc Honoré d'Estienne d'Orves Parc Naturel Départemental Honoré d'Estienne d'Orves
🕒 22.02.2026, 10:00 AM (duration: 1–1.5 hours)
