Blow up about three dozen small balloons. Make them about the size of your two fists put together and pear-shaped. Choose a color scheme to give your chandelier a sense of order. Primary colors, all pastels or one solid color would work well. You could also use clear balloons.
Thread a needle with clear, nylon thread and pass the needle and thread through the knot of each balloon. Pierce the knots only; if you get even a little of the inflated part of the balloon, your chandelier will start to deflate. When finished, you should have a long string of balloons.
Stick some sticky wall hooks to your ceiling around the light fixture you want to embellish. Place the two hooks on either side of the fixture about 8 inches from the bulb. Place the next two hooks about 10 inches from the fixture and the last set of hooks about 12 inches from the fixture.
Tie about 20 inches of nylon thread around the knot of your first balloon. Tie the thread into a loop and hook it over the first sticky hook next to your light fixture. Tie an 18-inch piece of nylon thread to the sixth or seventh balloon and loop that thread over the next sticky hook.
Decrease the length of your nylon thread by 2 inches each time as you continue hanging your balloons from the sticky hooks. This will create a long balloon spiral that is long and narrow in the center and becomes wide and short around the edges.
