You have all the time to rearrange or polish your flower arrangement. The flower design should look beautiful and artistic enough before you place your filler, when the filler is already placed, it would be harder to move your things around the area or place. Bear in mind that The filler are very fragile.
Colors are leaning toward monochromatic, for strong identity and style. Red and white are popular all year. Bright colors, like greens and oranges, will flow in the summer months. The Bohemian look, consisting of metals, browns, oranges and greens will emerge in the Fall. Combinations like "Khaki and Cream" are a good example of this Autumn vogue. Whites, creams, peaches and soft pinks remain, but bolder colors will come shining through. So, don't be afraid to try something different, just remember to keep it simple, elegant and unique.
