Form and function
When choosing furniture, consider both form and function. Choose a piece for the entryway that is not only visually appealing but has drawers to store your car keys and the dog leash. If you don't like clutter in the living room, look for tables where you can store remotes, magazines and odds and ends.
Buy things you love
Before you make a purchase, ask yourself if it's a piece you'll love years from now. If you answer "yes," go ahead and buy it, whether it's a bold blue couch, a lamp or a new rug. Regardless of trends or rules, don't be afraid to invest in pieces you love. Know these ideas for a stress-free home.
Choose the right rug
Rugs can be expensive, so it's important to choose the right size for your space. It can be tempting to purchase a rug in a design you love even though the rug is too small—but don't! Make sure at least part of your rug can be placed under some of your furniture or it will make the room look uneven. Find out the carpet stain removers to keep your rugs clean.
