I know what you are talking about. I also like decorating my house with natural elements. Recently, I made several wall compositions from shells and starfish which I hung in the living room. Besides, I like to combine different textures and materials. For instance, in the dining room I have concrete walls and bamboo pendants like these ones https://thaihomeshop.com/
. Also, I'm thinking about ordering 2 big palm leaf hand fans from the same shop, because the quality is just impressive. They will look nice on the dining central wall, and will match perfectly with the pendants!
