I have a "quilting" folder on my computer with sub-folders for quilt patterns filed by name, miscellaneous patterns (purses, etc.), Pantos, "how-to" tips and hints, quilt frame instructions, and sewing room ideas. Every once in awhile, I'll go in and clean out some of these files.
Patterns I've purchased or printed out are kept in 3-ring binders. Fabric requirements and a picture of projects I intend to make are kept in a little photo book in my purse for the trip to my favorite LQS. A small swatch of fabrics already purchased are included in the photobook and checked off the list.
I dunno if this is organized or just anal, but it keeps me in check.
