In my years of working at quilt stores, I learned that even the "top quality" brands of fabric are seldom wound straight on the bolts. We sometimes ripped off a few inches at the beginning of a bolt to see how bad it was. Our customers knew that we would rip or cut as they prefered. The experienced quilters could see by looking at the bolt whether it would be better to rip or cut.
Yes, we made sure to give them an extra inch or so in order to compensate for the frayed edges, but if it was cut, they had to deal with the straightening problem themselves.
I don't mind ripping yardage and have requested it when I have seen bolts that were not wound straight.
