On the way to the beach after work, we each carried our shoes and walked barefoot on the beach. There were waves on the beach, the rustling sound when stepping into the sand, and the traces of our footsteps. When I returned to the hotel, I immediately drew this inspiration.During the Art Nouveau period, wave curves, organic forms, and natural elements were widely used. The natural rhythm of the wave edge brings three-dimensional wavy lines, which increases the fluidity of the sofa's appearance and makes the overall look softer. The wave line is a very rhythmic curve, which is formed by continuous lines of the same or different curvatures. The geometric wave line is distributed in equidistant radius curves, and the force and reaction force it receives are uniformly alternating.The curve can act on people's spiritual world through vision and generate associations and resonance.
