I can't help you with that but I have a feeling, given the gorgeous scenery of that area you won't want to be spending too much time inside, even if it is a quilt shop. ;-) As I right remember, there isn't a whole lot in Maggie valley besides pretty scenery and the Wheels through time museum. Pigeon Forge was very touristy on the main drag but I bet there would be some nice shops off the beaten path.
I am sure some other members will pipe in soon with recommendations.
