Since you are an accountant, the statistics of quilting may be important. You could also reference the enormous online marketplace of products for sale- not just thread and fabric but online classes, tutorials, DVDs, & customizable quilting furniture, the hundreds if not thousands of 20 somethings to grannies and everyone in between blogging about their hobby (many with sponsorship from fabric manufacturers) & YouTube videos. First of all let's not skip Eleanor Burns... And who would have thought you could have a career writing fictitious books around the hobby of quilting? Jennifer Chiaverini, Beverly Lewis, and others... And what about the men in the industry from the country singer and quilt designer, Ricky Tims, to the men who are great longarmers? Quilting is not just a stereotypical little old lady ANYMORE! We are men, women, different colors, races, religions and occupations but we are a charitable group of folks. I would highlight the national charity quilt programs, the call for quilts in disaster situations (tornado, floods, earthquake/tsunami in Japan), local church groups, etc. It is a worldwide industry full of opportunities and fun.
