Our plans of the Andersen Designs are printed on a heavy paper by a commercial printer that prints all of our plan sets. They are shipped rolled. Our kits that are available for those plans are checked against our copy. If you have a set of plans from a different source there may be slight differences due to all printers don’t print a like.
