I mostly by pre cuts instead of yardage. I have never had a problem. I ignore the pinked edges, see them as solid. The directional prints are cut from yardage and the yardage is stacked going lengthwise. There are lots of videos online how pre cuts are cut and assembled by the big manufactures. A lot of shops cut their own pre cuts. I stay with the manufacturers cuts. Easier to get a replacement from the shop, most don't like to admit they cut wrong but have no qualms about replacing the manufacturer ones.
