True story:
My business travels once included carrying a briefcase on my travels through central and South America. One thing always found in same case was a JC Whitney auto parts catalog. Many customers and coworkers found that odd but few asked why.
That particular parts book was made with a thin paper in significant quantities. If ever I found myself at a quarto de bano lacking the necessary paper, a few sheets were removed from the catalog and crumpled until the necessary level of softness was achieved, then put to work.
Never be caught needing, and I refuse to use the left hand of the dark side religion.
plus jc catalogs are just plain fun to read sittin on the throne
Old phone book pages work like that, too.
