After pondering the many ways I could organize my pattern stash, I realized that using Microsoft's OneNote would be a great solution! I created two notebooks, one for patterns, and another for fabric so I can open both windows side by side whilst planning my next sewing project. I set up the notebook with pattern category tabs such as dresses, tops, pants, etc.. Cataloging the info for the patterns has been simple and relatively quick. Once I find the pattern online by using the pattern maker sites (I'm a member of ClubBMV) I simply right click on the pattern jacket, back cover with yardage, line art, etc., and click "Add to One Note." The page is then added to my notebook in a flash. The beautiful thing about OneNote is that it indexes it's contents so the notebook is searchable by keyword. For instance, if I want to find all of my dress patterns that are suitable for knits, I can search for dresses, knits, and wahlah they appear!!! Uber smart! Plus, I can print the notebook if I desire. I also saved it as a .pdf, which I then imported to my Droid phone so that my whole collection is handy when I shop for fabric, etc..
