In one sentence, describe what the following article is about:

Find a hoop depending on the size you want for your chandelier. For a larger piece that draws interest, pick a hoop that has a diameter of at least 30 inches (0.76m). This will allow you to wrap the lights multiple times. Hoops of this size can be purchased online or at many hardware stores. You can also purchase a hula hoop and use spray paint to give it a matte finish. Start at the end without the plug and wrap a zip tie around the hoop. Continue to wrap the strings of lights around the hoop, securing them as you go. Use as many lights as you need to illuminate the area thoroughly. Test the brightness of the chandelier by plugging it in periodically. The wire should still be flexible, so use one that is 20-gauge or lower. The smaller the number, the thicker the wire will be. Twist the wire to secure it to the hoop. The length of wire you use dictates how low the chandelier will hang. Use a wire cutter to trim it to the correct size. The loop will serve as the hanger for the whole chandelier. Make sure the wires are all of the same lengths so the chandelier doesn't hang crooked. Install a metal hook into the top of your pergola so the chandelier can hang firmly. Hooks can be purchased at any hardware store and installed either by screwing it in or with nails. Hang the chandelier in the center of the pergola to get the most even lighting. Plug in an extension cord to the end of the chandelier. Conceal it the best you can by running it along the wires and stapling it to the pergola. Use a darker colored cable that is more difficult to notice when it is dark and the lights are on.
Purchase a large metal hoop. Attach string lights to the hoop with zip ties every 10 inches (25cm). Secure low-gauge metal wire to the hoop in four spots at an even distance. Twist the wires together in a loop at the center of the hoop. Hang the chandelier from a metal hook. Run an extension cord to the ceiling.
