I don't do the ruler fold. I fold mine using the comic boards. I also put a note how many pieces to the board and approximate measurements. These are usually one or more yards. Up to 3. I have some on bolts that are more than 3 yards up to 6 yards. After that just more bolts. Since hurricane season isn't over with, I still have my clear storage containers stacked inside each other just incase I have to protect quickly.
