Decorating Long Tables?

You didn't state what type of party or for what age group or where it would be held, but...

You could decorate long tables by putting bowls or trays of water w/ a floating candle if you're permitted to light them & some "flower heads", just the flower part, not the stems, floating in the water.

You can spray paint the flower boxes in the colors of the party if you have chosen colors. Fill w/ dirt & some pretty annual flowers or even fake flowers. Maybe add some pieces of fake ivy or leaf garland. To look their best real flowers should be planted at least a week before the party.

You could set potted flowers / plants down the center of the tables & use them as "door prizes", "favors" or plant them in your garden. Sometimes this could be cheaper than other ideas if you find a potted flower you like at a good price.

Not knowing the budget ... you can buy some nice vases in different styles at Dollar Stores for $1.

You could get fake flower bunches & lay them down the center of the tables along w/ ivy or leaf garland, like a table runner. You can cut the flower bunches apart some to stretch them or cut the bunch apart & just scatter the individual flowers down the table w/ the ivy garlands. All supplies could be purchased at a Dollar Store. The flowers don't have to be continuous & thick on the table as long as it's continuous. It should look nice.

Go to the 1dollar store and buy the window boxes. Then if the colors don,t work for your theme, either decoupage some fabric on them or some material of your choice...its a cheaper way to do your table. Hope this helps, bonnie

ps Also you could spray paint them the color you need.
