Linda Byerline hates to admit that her business experience is self-taught. She was a stay-at-home mom with a nursing background when she posted an image of an extra cloth diaper she had made for her daughter on eBay.

Four years later, Byerline runs Happy Heiny’s, which provides cloth diapers online and in retail stores across the world.

“It completely caught us off guard,” she said of the immediate success of the company.

Byerline is planning to open her first “brick-and-mortar” store in El Cajon later this summer after moving the business out of her home this year. The shop will also offer parenting classes but she is determined to keep Happy Heiny’s from having “that company feeling.”
