My reception venue doesnt allow ANYTHING!! I didnt really pay attention to things like that when I signed the contract so now, as I'm trying to figure out decor for the room, I realized this sucks!! I don't know how I feel about balloons at a wedding reception, but I have seen on Pinterest if you put a marble in the balloon before you blow it up, it floats upside down, I don't know if this is true, I have tried a few random things from pinterest and not all things actually did work. Has anyone tried or seen this?! I figure I can blow up alot with no strings and let them cover the ceiling, just don;t want to buy 1000 balloons if it wont work! BTW I have also seen balloons with glow sticks in them on Pinterest, so I bought 200 pink glow sticks and tried, and FAIL. you can barely see the light at all. I need some kind of decor that doesnt need to be hung and I'm out of ideas for sure! Any creative DIY brides out there have any suggestions?
