One sure-fire way to make your home memorable? Take advantage of every opportunity to layer in a little personal style to your space. Adding (or replacing) a door knocker is a great example of exactly this type of decor-enhancing opportunity; they set the tone for a personality-packed interior, are usually VERY affordable and the install process is a quick, easy DIY project for a half hour on the weekend. Why have a same-old, same-old conservative - or even worse! - blank front door surface, when you can up the vintage-style charm of your place with one of these quirky creatures to greet you each time you arrive home?
