I live 20 minutes north of Macon and I am sorry to have to tell you that there are no quilt shops there. The only store that sells cotton fabrics is Hancocks---the other 2 that farscapegal mentioned only sell decorator fabrics.
If you are willing to drive north towards Atlanta (but not all the way to Atlanta), there are three shops you could visit. If you are interested in them, send me a PM and I will let you know where they are.
