so since balloons = party, it was sumamente important to have them at our shindig. i purchased the balloons from balloons.com in white and took them to my local Party City for them to blow up. they only had regular size and 36" ones but i wanted lots-o-balloons, so 36" was too big. purchasing them from the WWW ended up being the most cost efficient way (about $1 each!). i received them in the mail about two weeks before the wedding, dropped off the 7 bouquets at Party City a week before (with some extras, just in case!), then picked them up the morning of the wedding. i had borrowed our 15 passenger van from work and it's a good thing because balloons take up a lot of space.
i love the look of balloon bouquets. after we used them in the photos we tied them to the banister outside the reception site.
