If you plan to go to Cantril I highly recommend taking the time to go on to Rutledge too! It is also owned by the same people and is fantastic for fabric also. They have alot more fabrics than Cantril and is well worth the trip.
Rutledge is south of Cantril but I can't tell you how far,
It is an hour and a half from here and Cantril is 45 mins so maybe another half hour south of Cantril?
They probably have twice as much as Cantril for fabric or at least it seems like it. It is another little back water but is a big tourist attraction for the Rutledge flea markets they do every year.
