Painted window frames can become interesting decor.
Anyone can hang a poster or a painting, but creative wall art will give your home a style all your own. To keep your home from feeling cluttered, stick with a wall art theme throughout the house, or at least throughout the open areas. This doesn't mean your art should be uniform -- just keep an element that carries through, such as a color or medium, like cherry wood or brushed steel.
Poster Puzzle
Take someone else's art and make it your own by getting two large fine art or other visually pleasing posters and cutting them up into various-size rectangles. Frame each rectangle in its own picture frame, using the same style frame for each piece and making sure the pieces fill the frames perfectly. Hang them on the wall so the pieces are in the right order, top to bottom and left to right, but spaced out at varying intervals, as if the poster pieces had exploded out from a central point. Allow the distance between pieces to let pieces of one poster cross into where the other is hanging, creating a mixing of the two broken images. This works particularly well if done on a single wall in a larger room that allows viewers to stand back from the wall to view the full effect of the posters.
Household Items
Hang household items that no one would expect to see on a wall throughout a room. If fashion is your interest, find interesting hairbrushes, accessories and jewelry items that share a color theme or some other design element and hang them at irregular intervals on your walls. Show off your literary flair by spreading your bookshelves out over your walls. Use floating glass shelves with display stands to create a whole-house library rather than a few crowded bookshelves. Consider a stylistic room swap, so items commonly found in a kitchen, such as copper pots or artistically shaped utensils, hang on the living room walls. Hang bedroom items like alarm clocks, stuffed animals and slippers on your kitchen walls, then use living room items such as newspapers, magazines, playing cards and serving trays in the bedroom.
Windows and Doors
Create a whimsical or even mysterious look by hanging false windows and doors as art throughout your home. Cover the windows with curtains that match your other decor or leave them open and paint the frames in bold colors. Doors can be painted and fitted with doorknobs and hung straight and on hinges that open or at odd angles to add a sensation of motion to the room. Paint the windows and doors solid colors that change with each room, complementing the wall color, or sponge them with textures or abstract designs. For rooms without a lot of wall space, add window-like crossbars to photo frames to simulate the look of tiny windows and continue the theme.
