A Japanese lantern is a paper lantern made by gluing paper over a wire or bamboo frame. The paper is decorated with Japanese themes and a bulb or candle is placed inside. The lantern is used for festive occasions.
Remove the object which served to make the frame of the Japanese lantern. Now use the extra bit at the bottom to form the base. You can just stretch the wire across the bottom – like a diameter of a circle if your shape is spherical (like a no smoking sign) or like a diagonal if the shape is polygonal. Mirror the same on the top. Now use rice paper (colored or plain) to cover the lantern.
You could wrap the paper around the lantern or if you are looking for a better finish cut the paper into strips and then stick them onto the frame. The edges should overlap and should be glued together. Once the paper is glued on, let it dry and then paint or draw the theme onto the paper. You could choose your own themes or use the help of a Japanese design book. It is after all a Japanese lantern.
Instead of making the Japanese lantern yourself you may also buy it, though that may prove expensive. There are many retailers on the Internet who would sell you Japanese lanterns of different designs, colors, and shapes. If you browse around you may get good deals as well. When you buy just make sure that the design and theme of the lantern fits the purpose you have in mind. Also make sure they are made using high quality rice paper.
A Japanese lantern or Japanese Lamp is made of sheer material, typically paper, and if you are feeling luxurious, silk. The paper could be either plain or decorated to reflect Japanese themes or any theme the maker chooses.
They are hung on wires and will be lit from inside using electric bulbs or less frequently candles (though candles do pose a fire hazard unless you are very careful). The light lights up the patterns on the paper to achieve an exotic and ethereal effect. These lanterns are used as decorations during festive occasions. You could use them for parties, during Halloween, or even have them for every day use out in the patio or the summer home, the pagoda or your garden. They can be used as decorations for a romantic evening or as theme decorations in restaurants. In short, you could use a Japanese lantern for any decorative purpose.
If you want to make a proper Japanese lantern you would need to make wire frames (old lanterns used to have bamboo frames but bamboo is more difficult to manage) that will define the shape of the lantern. If you have skill in making wire frames then you can make a frame of your choice on your own. If not, use an object of the shape of your choice (if you want a spherical lantern use a ball) and use the wire to wrap around the object. You should leave some bit of wire at both the ends to form the base and the top (where the electric bulb will hang).
Typically this would be about one and a half times the bottom of the lantern. Now wrap the wire around the object (with some distance between each spiral) to form the frame leaving enough space at the bottom for removing the object and at the top for inserting the light bulb.
