Dritz makes a pattern storage box that is perfect for these kinds of patterns. I have several, one for "made" and one for "unmade" , one for "what was I thinking? I won't make that!" I used to get them at Hancocks but now I think you can find them at Amazon and other sewing supply places. If I make changes or templates, I then put them in a sheet protector and put in a binder. And when I first use one of those patterns that come in a plastic sleeve, I scan and save in my computer. That way if I mess up the pattern in some way, I have a copy of the original in perfect condition.
