I would use the pattern if it were what I needed. I usually want something else. It would not save me much. My laser printer costs me less than $0.02 per sheet to print.
I wanted to mention backups. When I scan a book or pattern, it gets backed up offsite as soon as I save it the first time. When I edit a pattern, it immediately gets back up, and the old version gets saved for 30 days in case I change my mind or do something stupid like write over it. Deleted files also are saved for 30 days. I also periodically run manual backups. I have at least four copies of every scanned pattern or book., each stored in a different device of every scanned pattern or book.
If it isn't offsite, it isn't backed up.
If you haven't tested a restore, it isn't backed up. I can tell you how many times I have been given a blank tape to restore someone's data. Not a fun day.
I know someone is thinking, "I don't have to back up my paper books." Think fire, flood, hurricane, tornado, or the dog eats it. Your disaster recovery plan by all new stuff.
