This is a great technique for about 300 - 400 patterns. I don't have near that many and lots of people have way more than that. I don't think I could ever use that many - ever. Thank goodness I never got too involved in making things from patterns. When I was younger I used to sew clothes - but now I just quilt. I probably only have about 40 patterns total, So I am able to keep them all in one drawer - thank goodness.
