I was using binders and sheet protectors. It's a nice way to be able to browse the patterns, easier than using file folders, although the smaller patterns in bags, I have in drawers with sewing patterns. Those are a little thicker, so I didn't feel that they would fit nicely in the binders. But then I got pattern overload, so I started scanning patterns or downloading them as PDFs. It's easy to page through those on the computer. I have a hard time finding things by file name, though.
