Leonardo's Drapery Studies

I started a large painting today with a lot of drapery folds, and it made me want to have a look at Da Vinci's drapery studies.  I couldn't find one page that contained a large grouping of them, so I decided to put one together here.  Although I probably should include them with titles, materials, and dimensions, I really don't feel like taking the time.  That information is easily found on a quick Google search.  Hopefully others get as much from studying them as I do.
