Pippa Middleton made heads turn at the royal wedding, but she intends to be known for something other than her posterior and her in-laws. A year and a half later, she’s written a book, Celebrate: A Year of Festivities for Families and Friends, with wisdom gathered from her days working at an event company and for her parents’ party supply business. Pippa shows how you can make your soirée just as special as any thrown at Buckingham Palace—and on a commoner’s budget.
