I like yngldy's idea of a traveling quilt shop, especially since you're in a rural area. If that's not feasible, I'd try to brainstorm ways to get store traffic in addition to offering fabric and notions. Classes can bring in people; so can BOM's where each month they stop in for the next installment. Christmas Open Houses are always popular, as is a Christmas in July event to get a jump start on gift making. Finally, I'd open an online store to supplement your B&M; either on Etsy or eBay so you aren't totally reliant on your local shoppers.
