For big-impact table decor on the cheap, consider carnations, which come in so many colors. Long used as inexpensive filler, the familiar flowers have a chic style all their own when clustered in modern, minimalist vases that offset their ruffled softness. Plus they're readily available throughout the year. Arrange them by color (we like this spectrum of fiery orange to pale yellow) for an array of color that really makes the gradient.
