Lay out all of your art pieces on a flat tabletop or counter. Move the art around to see how different arrangements would look. If you want to mix the different pieces of art for a multicultural, eclectic effect, choose pieces that complement one another in color, form and style. You can always choose to keep the African, Dutch and Victorian art separate from one another.
Consider the availability of wall space in your home. Avoid installing the art in a place that receives ample amounts of sunlight; sunlight will fade paint. If you want to install the art in a living room with large windows or a sliding glass door, place the art on the same wall as the windows or door to avoid exposure to direct light. Make sure the space has bright artificial light so your art will be prominently displayed.
Hang the art. No matter how you decided to hang the pieces, whether by culture, artist or color, you need to think of the separate entities as one picture. This will help you arrange them on your wall without large gaps between frames or other problems. Use a measuring tape to find the center of your wall and mark it lightly with a pencil. Use a hammer to place a nail at the spot and hang the first piece of art. Using the frames or the pieces themselves to help you determine how to space the works. Also, use the shape of the wall to help you decide whether to hang the pieces horizontally or vertically. Repeat until all of your art has been installed.
