Great minds think alike! I do the same thing.
I also put post-it-flags on very special patterns I want to make in magazines and store them in a separate magazine holder from the rest. Meanwhile I'm also trying to go back through the scads of magazines I've collected that do not have anything I'm interested in making and will pass them on to a quilting friend.
Unfortunately that project is probably going to take years as it's waaaay down on the "To Do List".
