Interesting. This factory might've also had to dealt with that degree of variation. IIRC (unless I'm thinking of a factory for a different customer), their processes include a per-unit container that moves through the production line, and the container starts with various materials that will go into that unit. So I guess that's one way they could ensure that all the outer fabric came from the same part of the same roll.
