For printed patterns, I also use a binder with the sheet protectors and divided into categories: baby, bargello, stars, etc.
For those on the Internet I save in a folder, as well. The main heading is "quilting". These are also sub-divided into other folders in the same way: blocks of the month (by year), kitchen (with its sub-divisions: pot holders, table runners), etc.
I have far more saved than I will ever complete in my lifetime, and when they are saved on the computer, no printing is required.
