Every door in your house, be it bedroom or bathroom, is bestowed with its own personality when it is fitted with a dramatic door knocker. Paint each door a different bold color to mimic old European doors and "distress" the paint-job by rubbing lightly with sandpaper or adding a watery white wash over the newly painted surface. Adorn each door with an antique door knocker featuring classic Gothic imagery. Use the same door color in the room to which the door opens -- either in wall paint or accessories -- to tie the space together.
Show off your door knocker collection by hanging the knockers in a vertical line down a narrow wall in your home. A narrow architectural detail that divides rooms or borders windows and doorways is a naturally defined area to showcase your knockers. Paint colorful squares on the wall to serve as a nostalgic backdrop for each door knocker and make the narrow wall display a focal point in the room.
Mount door knockers on a long plank of wood in a horizontal fashion to hang over a sofa in your living room. Paint the wood a vibrant color or stain a rustic piece of wood a deep cherry shade. Distress the wood to give it an aged look. You create a space full of texture and architectural details when you mount the door knockers at equal distances apart on the wood and hang it over a long sofa. You can also mount each door knocker on it's own square of painted or stained wood and hang in a row above the couch for a similar effect with more versatility.
You can take advantage of the look of decorative and unusual door knockers even if you don't own them. Collect photographs of historic and antique door knockers from online photo sites and print them from your home computer. Frame the images with matching white matte and black frames or create a photo collage by framing all the images in one picture frame. Decorate a kitchen, bath, office or living space with the framed photographs to bring a door knocker element to the space.
Show off your eclectic door knocker collection in the bathroom by using them to hang your towels. Many door knockers have a hoop-like knocking mechanism through which a towel can be threaded. Replace your existing towel rack with a few door knockers hung in a horizontal line. Extra fluffy towels will demand a standard rack, but door knockers can still be hung just above the rack to get a similar feel in the space.
