From the designer:
Exclusive handmade interior decor elements are valued for an artistic forms, naturality and originality.
This special collection was created following the conception “closer to nature, but also suitable for a modern interior”. During the day it is an active interior decoration, and on the evening time – a romantic candle light creating unpredictable play of shadows.
Sculptural decorations are made of used paper. Paper mass mixed with glue, dried out and treated acquires the characteristics of tree anew: it gives solidity, natural qualities, color and texture. The piece is polished and covered with varnish, thus it is not afraid of humidity.
