I never cut up long yardages until I am ready to use in a project. Then plan for what I want to do and then know if I can cut one yard chunks at a time. For cutting I can then do 1 yard at a time so that it stays straight. I do not take a real long time to fold that long yardage precisely selvage to selvage when I am just putting it away. Life is too short - I get it sorta there and put it away. When its time to use it then its time to fuss with it.
