I have a 3-ring binder, very full now, and organized as to type---Christmas, baby, kitchen, paper-piecing, bed-size quilts, lap quilts, etc. Topics work for me though maybe not for everyone else. Within those categories, I have not organized things so it is an enjoyable search as I look at things I may want to do one day on my way to the thing I am looking for.
When I find something I like on line I print it out and lay it inside the cover of the notebook until I have a few and take the time to punch the sheets. (You can also buy pre-punched paper at office supply stores so then printouts would be ready for immediate filing.) I keep that notebook and my quilting books in a bookcase near my work area. In 2011, I will need to start a new notebook!
