You HAVE to go to Mary Jo's. They have absolutely everything any sewer could want. It's an opportunity not to be missed. I don't know about any quilt shops in Greenville, but you could do a Google search. I believe there's a quilt shop in Central, SC (about 40 miles from Greenville close to Clemson) but I don't know if it is still open or not. I think there's a quilt shop locator app for the Iphone and Droid phone but I don't own one of those phones so of course I don't have the app either. Enjoy your trip and let us know what you find!
