I could have sworn I uploaded a project when I took this class.  Oh, well.  

I did all of my organizing about two weeks before the news dropped about the reformatted brush libraries in 5.4. Oh, well.  It was a good exercise in getting familiar with all the brushes I had collected and eliminating duplicates.  

I now make a new brush library for each new collection.  No guesswork involved if I go back to an old project.
