The last principles we need to discuss are unity, variety and electric style.
Unity is when all the parts of a design relate to one idea. A harmonious design would be an example. You can use items that have similar characteristic.
Variety is when different styles and materials are combined. But remember don’t go overboard because it can become overwhelming.
Last is Electric style. This is when you mix furniture of different styles and possible from different periods. For example you can mix modern with classic. But remember to use items with similar proportions and similar finish.
