Tall centerpieces could be dramatic! I love a see-through vase, though, so guests can talk across the table. I'd add in tall curly willow branches coming out the top, too, with purple orchids tied here and there. The goal is in the end, to have dramatic arrangements that aren't so round and perfect.
White table cloth, gray table runner, stacked tin can vase, fire works bouquet, long ribbon (yellow) little thin shoots of feather, rounded nail head (button look). Little candles, and table number idea at the base of centerpiece.
