To create an informal feel for wedding tables, or just for a pretty arrangement at home, instead of one large vase of flowers use a mix of vases of assorted shapes and sizes.
Petite vases, even egg cups or votives, show off delicate stems and individual blooms.
For a stylish display, stick to one colour palette, but use groups of one type of flower in each vase. You could add decorative details like lace to link the vases. Or for a cheaper alternative, try textured paper or doilies. Dress the table with coordinating accessories.
A combination of tall and shorter vases adds depth and interest to the table centres. A single colour theme for the vases and flowers keeps the display clean and modern. Simple.
