If you are flying into Charlotte, and driving to Myrtle Beach, you should take the time to go to Mary Jo's. She is on Cox Street in Gastonia. 32,000 square feet of material. and a fantastic place to shop. about 20 minutes from Charlotte
Here is the link to her store, and you can take a virtual tour. The greatest place to buy fabric on the eastern seaboard. :-D :-D
I live about 1 1/2 hrs away, and go as often as I can.
