Complete the coastal beach house theme in your kitchen with coastal-inspired window treatments. Opt for light and airy curtains in shades of white or blue to mimic the look of billowing beachside drapes. Choose fabrics with subtle patterns such as stripes or seashell motifs to add visual interest. Sheer curtains or bamboo blinds can also be used to filter natural light and create a relaxed and breezy atmosphere. These window treatments will enhance the overall coastal aesthetic of your kitchen.
