There is a reason I don't buy fabric from shops that rip and it occurred to me when I saw a friend at her beautiful large sit-down hand weaving loom. When the loom is "dressed", the strongest threads run up and down (or north and south as you are seated), and the weaker threads are the ones attached to the shuttle which then are worked in between the up and down threads.
Ripping causes the main threads the pull apart with resistance which causes bruising. This bruising can vary from fabric to fabric and can stress the fabric as much as 6 inches into the yardage. When I lived in Texas in the 1980s and 1990s I actually knew of a couple of well known quilters whose winning quilts had been ruined when the bruising showed up in their quilts after handling and hanging.
