When you think “farmhouse” theme, you should think of rustic colors. Imagine deep umber shades and deep purples with faded gray shades and silvery accents. You could also use deep reddish browns to celebrate the earth and bring the idea of a harvest through. Be sure not to only focus on the colors. Consider patterns and textures too. Farmhouse bedding thrives on small details such as pleats, folded elements, ruffles, and lace-up elements.
