Banners & Balloons

Number Balloon It comes in other numbers of course, and you can also spell out the birthday child’s name in mylar balloons if you wish.

Here’s my favorite tip for mylar balloons: Buy a balloon air pump at the Dollar store (or wherever), pump it up and place it in a focal spot, instead of having it float with helium (on top of the mantle, on the gift table, etc. and secure with some painter’s tape on the back). Mylar balloons last FOREVER with regular old air in them. And you don’t have to make a trip to the party store to have helium put in it. I’m all about not having to run errands the day of the party!
