Some people look at a hole and see empty space. Others see opportunity. That’s what Sheri Schmelzer spotted a few years ago when everyone—including her three children—started wearing Crocs, the colorful shoes dotted with holes.

“My kids and I were clowning around, and my eldest daughter, Lexie, got the sewing kit out. I brought one of the Crocs, pulled some buttons, rhinestones, and fabric out of the kit, and stuck them in the holes. Lexie said, ‘Mom, I love that!’”

Sheri and Lexie, then seven, spent the rest of the day filling holes in the family’s 12 pairs of Crocs. Every look-alike shoe was suddenly unique. When her husband, Rich, experienced in setting up businesses, came home later that day, says Sheri, “I could see the light bulb go on over his head,” Crocs had sold millions of pairs of shoes; the couple figured they could create a business simply by riding the wave. Rich refused to let a decorated Croc leave their Boulder, Colorado, house until he’d filed a patent.

But first they needed a name. “Rich and I had seen a movie where Meg Ryan says to Tom Hanks, ‘I’m such a flibbertigibbet!’ That became my nickname, so I called the business Jibbitz.” While Sheri designed, Rich strategized. They decided to sell the charms through a website, Jibbitz.com<http://www/jibbitz.com.>

Six months later, in February 2006, Sheri was doing so well that Rich left his business to work with her full-time. She was making hundreds of Jibbitz to order, by hand, by herself, in their basement. And filling those holes wasn’t as easy as it looked. The bigger the shoe, the bigger the holes; it took six models before Sheri figured out how to make her charms one-size-fits-all. Later Rich found a way to get plastic Jibbitz manufactured in China.

Someone at Crocs was sure going to notice the charms—after all, the company was headquartered (总部设在) just ten miles down the road. Duke Hanson, one of Crocs’ founders, spotted Lexie and her Jibbitz at the local pool, handed her his business card, and said, “Have your mom call me.”

Sheri and Rich met with Crocs executives, but no one suggested buying the company. Sheri was actually relieved because she wanted to see if she, not Crocs, could make it big. And she did. In December 2006, Crocs bought Jibbitz for $20 million, with the Schmelzers staying on board.

A. the Schmelzers kept improving to make their business successful

B. Sheri does not trust others when it comes to designing Jibbitz

C. making the products unique is key to business success

D. Rich made a lot of sacrifices for their family business
