3 ring binders are the best. I alphabetize. My manuals are in binders also with charts for needles and thread and quilt sizes. One of my manuals pages had a page 1/2 torn. Went online to print the pages, stapled it into the manual and put it into a sheet protector. ALso printed a photo of my machines and attached to the manuals. I also have a binder with quilts I'm working on and who those quilts will go to in case of an emergency.
