In Greensboro, go to Calla Lily, located at 2917 Battleground Ave # E (behind the Longhorn Steakhouse. I longarm their shop samples. They are always getting new fabric lines into the shop. Nearby is Studio Stitch. A little further is Ye Olde Forest Quilt Shop.
In Winston Salem, there are quite a few: Village Fabric Shop, Sew Original, Knit One Smock Two.
