I store most of my patterns digitally. Most were downloaded from a website. Many I copied from a website, pasted into a word document and edited to make it a smaller file(cut unnecessary pictures, reduced sizes of pictures, etc). A bit of work but I find if you bookmark a web page it could(and probably will) disappear over time.
I do have a supply of many years of various quilting magazines. I started scanning and saving patterns from them digitally but find it slow and a little difficulty with some magazines whose page sizes are borderline too big. I'll never be able to make all the patterns I've saved so may stop scanning and just pass the magazines on to others.
I think download, editing or scanning is the same or less time than the printing and organizing in binders, although I've never done that. Also digitizing means no paper use or storage until you really decide to make a pattern.
