On a roll of seconds it is quite possible that you will see NO flaw at all... In every case, if there is a flaw at all, it is "cosmetic" only. i.e. creases, stains, varying dye, or even a smashed fly. All cloth is usable and you can always cut around a blemish if present. We sell ALOT of seconds and I can count on my left had the number of times fabric has been returned. You'd be surprised at how many kites are manufactured with second quality fabrics...
