I too would like the pattern.
Someone mentioned that maybe they could use it for a book cover and it reminded me that when my kids were in elementary school and had to cover their textbooks, I used to make them covers out of fabric. I did exactly like one made out of a brown bags but sewed the top and bottom of each end that slid onto the front and back covers. They lasted all year and the kids could pick out fabric that reflected their interests. I used to like making them each year.
