I ordered some, just out of curiosity, and when it arrived, I unfolded each fabric - didn't find any visible faults in any of it. I used my handy-dandy thread counter (R.O.S.E.) and found it amazingly regular in weave. No complaints here. I wouldn't hesitate for a minute using it for a quilt backing, or even using it to cut patchwork pieces. I'm still wondering why it's labeled "seconds".
