I put them in clear plastic sleeves and into binders. If I pull a pattern that I know I am using with fabric, I put an index card in that sleeve with "a reminder" of which pattern and fabric- otherwise I forget what I did with it. AND I have limited myself to just TWO 3 inch binders to hold purchased patterns and magazine tearouts or freebies with purchase. My online freebies are kept on the computer and during the winter months when it is so cold- I grab a cup of tea and spend some time looking at them. Ones I have used and know that I will not make again get re-labeled ZZZ "name of pattern"- that way those are at the end of the quilt pattern file and I don't have to sort through them. When I make something from a tutorial, I take a picture and in a notebook write the web address - just in case someone asks.
