Wedding themes? Ready for 2013 wedding

my wedding is in july, am sooooooooooooooo excited.
now i have no idea what theme should i use or maybe make it simple and use colour themes.
i thought i would make my own centerpiece using craft flowers, and make invitaions.
but dont know how to decorate the guest book table.
so, i need to know what colour themes to use for july, and how to decorate the venue.

You do not have to have a theme if you do not want to...you could always use something simple like two hearts or love.
As for colors, you could really do whatever you want. I would just pick your favorite colors. Or, if you do not have a preference I would look at the decor in your venue. If you use colors to match the decor of the venue you can save some money with decorations because everything will blend nicely together.
What type of venue do you have? A lot of the times the type of venue you choose can determine the decor. Do you need to start from scratch, like a hall? Or are things already decorated?
Here are a few ideas that you can use in regards to centerpieces, etc. Although, I will warn you that if you are going to try to do the centerpieces yourself you should start soon. I originally started out wanting to do it myself, then realized how hard it was to make what I wanted look nice...so, just some advice to start soon.

go to places that sell things to make to get themes and ideas, try walmart and orientaltrading.com and saveoncarfts.
You can use red white and blue as well,
or a fireworks theme with red, white and black as your
colors that would be awesome. Look around... pick a
theme and stick to it.
