Yeah,irritating. I was in a shop a while back, got 4 yds. Obviously, the bolt had been cut wonky. The clerk laid it straight on the table, needed to cut almost 3 inches off to make a straight cut. I told her If she just measured from the straight, she didn't need to cut off the wonky part. "OH, no, no way, I couldn't do that." So she cut it, then THREW THE WONKY PART IN THE TRASH!!
