I do not photocopy patterns because Of copyright issues. I own about 20 magazines and 20 books. I have cut myself off from buying more. I have the magazines all stored in one 5 inch binder with three ring magazine holders for them. I open the magazine to my favorite pattern and put it in the insert there so I can flip quickly to it. Any books or magazines that I fall out of love with, I pass along. I have another binder with individual patterns I bought and free patterns from the Internet.
When I am working on a quilt, I store it in a box with the fabric and any special rulers, tools, threads, etc.
