Rustic Decor: A Return to the Basics
Some decor styles are more difficult to achieve than others, but a rustic style could not be more simple. Limit yourself to the essentials, without any bells or whistles, and you will immediately feel a sense of comfort and warmth, like you would at a country chalet.
The natural and country-inspired elements of a rustic decor, which harken back to a simpler time, can also be combined with other decor styles, such as an industrial or contemporary look.

Au Naturel
Choose raw, natural materials such as wood, brick or stone. For sofas and bedding, opt for fabrics made of natural fibres, such as cotton or linen.

Shapes, Textures and Accessories
To successfully create a rustic look at home, focus on straight lines and unrefined textures. Then add handmade or old-fashioned accessories, such as old furniture and burlap rugs.

A touch of Colour
Although natural colours, such as white, beige and grey, are often used for a rustic decor, feel free to add a few touches of colour. For example, plants will add freshness and life to a room while maintaining a rustic feel.
If you decide to use fake plants, don't skimp on quality. They must be as realistic as possible, both in their shade and their composition.
