Gail, I keep mine in 3-ring binders. I slip a picture of a favorite quilt into the front and back covers, so it's obviously my quilt notebook. I put page protectors in the binder. I rip my favorite patterns out of my magazines and put the picture in and the pattern behind it (in the sheet protector). I limit myself to two binders. When it a binder gets full it's time to go through it and get rid of any pictures/patterns that no longer appeal to me. Then I have room to add a new one that I like.
I like this system because I always have plenty of pretty pictures to look at, I fairly regularly go through and cull things that are no longer appealing to me (why keep everything for 20 years when styles and my tastes are changing?), and I'm not trying to store complete magazines-I'm taking out only what I want then pass the magazine on to someone else.
