Decorations

I was wondering if anyone knew of a place that you can buy inexpensive 12" or more snowflakes? i have looked everywhere and all i am finding are ordiments for christmas. We are getting married in january of 09 at a lodge just off the lake and our theme is winter wonderland. We wanted to have snow covered tree branches and candles as our center peices. Snowflakes hanging from the wood beams up above. We are also using white christmas lights all over the room. It will be amazing but i need those snowflakes... Pleas help! ~ Jessica
