Moda's comment on higher thread count doesn't make sense. Higher thread count, less fraying, unless the threads are not "locking" on the selvages.....then the whole piece would keep raveling....now that would be a problem Moda needs to solve. Sometimes with a loose thread on a garment, you can pull on it and keeps raveling back and forth on the piece....it is not locked on either side, by a selvage or your sewing.
