Mixing and matching different rug patterns and sizes is a great way to create a visually stunning and dynamic space in your home. When it comes to rug patterns, the key is to choose designs that complement each other rather than clash. For example, if you have a bold and intricate patterned rug, pair it with a simpler and more geometric design. This will create a beautiful contrast and balance in the room. Don't be afraid to mix different textures as well, such as a plush shag rug with a flat weave kilim rug. This will add depth and interest to your space.
In terms of rug sizes, it's important to consider the proportions of your room. If you have a large open space, consider using a 10x14 area rug as the main focal point. Layer smaller rugs on top to define different zones within the room and add visual interest. For example, place a smaller rug under a dining table or in a seating area to create a cozy and intimate feel.
