I put all my patterns in page protectors and then aI file them in a file cabinet in my sewing room. I file them alphabetically in hanging folders. I have some folders for table runners, aprons, etc. I also have a spread sheet in excel in which I list all my patterns by name company and author if listed. Then I can quickly look at this file and seem what I have. I also label the type of pattern, applique, paper piecing, etc.
