Balloon Centerpiece Ideas

I need some ideas pretty original piece and cheap as I can do myself. The theme of the party is a masquerade, in dark colors.

If I use balloons or flowers?
I also masks I can use for centerpieces.
The game will be in a garden with a swimming pool, if that helps.

All ideas are welcome, my party is Friday, so I gotta make a decision soon. Thank you!

Balloons Missing mystique of a masquerade .. I would go with flowers.

Here are my ideas, we hope they will help you. You can find most of the materials at a dollar store or craft store like Michaels.

A) Get a glass dish or bowl, this is not too deep and fill it with potpourri dark. Stick stems of flowers (make sure they do not poke too high) in pot-pourri, and place a mask glitter on top.

B) Pick 3-5 branches with interesting shape (not right) and apply Stokes random glittery paint. All twigs and equality in the middle with large single tape. Lay the wire on your table so that most branches to stick. Wrap and draped necklaces of pearls and pear false or ribbon branches. Make a mask for the middle of the beam twig.

C) Get a large multi-arm candle and wrap the base with black feather boa (dollar store has them in the children's section of the party). Hang a mask on his arms, and finish with flickering candles. Like this:

D) Fill the bottom of a glass vase with sand, stick a candle in the center and put a necklace of beads / faux pearls around the candle. Fill the vase with water to cover halfway candle (and sufficient to completely cover the beads), and sprinkle with glitter so they float on top. random scatter of feathers around the vase.
