How can i make a rattan trunk darker?

To darken a rattan trunk, you can apply a wood stain or dye specifically designed for natural fibers. Start by cleaning the rattan surface to remove any dust or oils, then test the stain on a small, inconspicuous area to ensure you achieve the desired color. Use a brush or cloth to apply the stain evenly, ensuring it penetrates the material. Finally, seal the trunk with a clear topcoat to enhance the color and protect the finish.
