The one in Harriman is Loose Threads. I don't know the name of the ones in Cookeville. There are several in Knoxville. The ones near the interstate are Gina's Bernina, Sewing Machines Etc, Mamaw's Thimble, Cat (or Kat) Lover's Quilting, and Dizzy Divas.
Enjoy your trip. Our area of the country is beautiful in the fall.
