i used to keep all my mags. found the same problem as others that over time my wants, needs, likes changed. also, many of the "new" patterns are just different fabrics. then i realized that with rare exceptions i find something i like in almost every mag. this led me to decide to let go of the mags and just enjoy the new ones. i keep about one year worth, go thru them periodically and remove the patterns that still appeal, put them in binder.
the other thing that helps is the digital subscription. really like that. i can go back ten years online and i don't have to make storage space.
hadn't thought about scanning the pages i save. i may have to hook up the scanner and get to saving.
