What a "why-didn't I think of that" kind of idea. Put a wine or margarita glass in the middle of a large bowl for instant chip and dip set!
Tape balloons around the room while the birthday boy/girl is sleeping. Don’t forget to set up a video camera to record their reaction when they get up in the morning. totally doing this next year for selah's birthday. or maybe just for a fun surprise wake up one day. :)
Use plant stands to put platters on for cupcakes or different levels of serving food at a party. Great idea and inexpensive!
Glowing Pool Lanterns from The Classy Housewife. "All you have to do is place a glowstick in a balloon and then blow the balloon up. You can use variations of different color balloons and glowsticks to add a little pop to your outdoor party decor." red balloons with glow sticks in them hanging from trees in the field would look really cool
