An interesting party decor idea is to place balloons inside other balloons. This can be accomplished easily by first inflating a large balloon. Using a small stick, push a second, smaller balloon inside the larger one and then inflate the smaller balloon while it is inside the larger one. You can then tie up the second balloon, leaving the smaller one inside the large balloon. This can be repeated with multiple small balloons, so your balloons will have a unique and interesting look. This tutorial is perfect for anyone who would like to bring a little more style and flair to their party.
