Got the creativity bug? Don't overlook the built-in canvases every home has: doors. They're already "framed" and offer a pre-designated area for creativity. If it isn't used you can remove the doorknob and blend it in with the rest of the wall. As long as you have enough exits in your home or apartment you can seal off the door so that it stays put and isn't used.
Decorate the door with paint, appliqués, clippings or decorative mirrors. Paint it with chalkboard paint so that you can change its design every day if you like. You can also change the door's decor depending on the season or upcoming holiday. Lastly, you can also use the door simply as raw space. For example, you can place planters and vases around the door or create a border of photographs extending from the doorframe. This will create negative space, which is a unique decorating technique.
