Here are some other ideas to make your red carpet complete:
Make your red carpet super official, by adding red velvet ropes for protection. You know, just in case your party is stormed by fans -- or the neighbors. Here's one option from Global Industrial, starting at $26.95.
Add a few lights to your red carpet to make it the perfect photo opportunity. After all, the whole point of a red carpet is to get the perfect shot. You can grab professional lights for as low as $50 from Walmart, or $16 from Westcott.
Have you, or a few friends, pretend they're paparazzi for your red carpet. If you use a smartphone or a Polaroid camera, you'll give your guests memories immediately. It could also serve as a pretty cute party favor.
