Save money - get the wedding party to pay for their own flowers. And make the center pieces yourself.
A very expensive item to buy for weddings are the flowers. You will save a lot if the wedding party pays for their own flowers.
Another way to save money is to make your own center pieces.
A great idea is to buy vases or candle holders from a dollar store and fill them with coloured water or flour petals and maybe even floating candles.
