Paper lanterns emit a soft, warm glow. Positioning the lanterns all at the same level may give the room a uniform brightness. On the other hand, positioning the paper lanterns at different distances from the ceiling can give the room unique angles and perspectives that otherwise might not be there. Hanging lanterns at different levels can also give off the impression of weightlessness, and make the overall atmosphere of the room more comfortable and inviting.
This decoration idea is similar to the multilevel paper lantern idea. Instead of using one specific size and shape paper lantern, purchase lanterns of all different shapes and sizes. Japanese paper lanterns are different than Chinese ones and American ones, and all could be used to reflect a blending of cultures. Rectangular, boxy paper lanterns emit different light patterns than spherical lanterns, and both can be used to achieve the best light effects.
Buying paper lanterns can be quite expensive if you plan on buying multiple lanterns to hang off a ceiling. You can create your own paper lanterns by purchasing wire to form the lantern frames and rice or tissue paper for the lantern panels. Bend the wire into the desired frame and paste the paper panels over top with paper glue. You can use paint to give the lanterns your own artistic touch. Hang the lanterns from the ceiling when you're done.
It can be an electrical hassel to install new lighting for paper lanterns. Use preexisting lighting fixtures on the ceiling instead to give paper lanterns their much-needed glow. Attach paper lanterns to the lighting fixtures with string or wire, and make sure they hang evenly. You don't want the lanterns to be directly touching the bulb, which could cause a fire. This idea makes use of what you already have, so you can save money and still have a unique living space.
