Kate Middleton's younger sister, Pippa Middleton, dishes out how to celebrate the spooky season, just like how they used to when they were younger.

In her party-planning book, Pippa Middleton, revealed how she and her family used to celebrate Halloween. Since the Middleton family business revolve around throwing parties. One of her favorite parties to plan is Halloween, and now that many are dressing up in their costumes, Pippa tells how to decorate houses and throw a scary affair this season.

"As a child, I felt that Halloween was a time when creatures of the night suddenly came to life," writes the younger Middleton in her book. She recalls how her family used to keep the vibe spooky enough for kids and adults alike.

"We would turn off all the lights in the house and let flickering candlelight conjure up scary shadows and imaginary figures lurking in dark corners." further wrote Pippa. This is also a simple and effective way to scare guests when throwing Halloween parties.

When not in the mood to decorate the party venue, Pippa also shares how to maintain the Halloween vibe by whipping up "gory" food on the table.

"I frequently celebrate Halloween over a supper with friends. It's a wonderful excuse to let your imagination run riot with gory-looking food and special effects." shared Pippa. Putting cut-out tomatoes on the tip of thick potato fries look like monster fingers. Playing around with red food coloring is also a fun way to make it seem like blood is running through the dining table.

Meanwhile, Pippa gained the number 10 spot in a recent poll searching for Britain's most naturally beautiful women, while her older sister Kate, lead in the number 1 spot.
