Degas book, original sketch from life, Degas study of a male violinist, and my working sketch on Bogus Rough paper.
How interesting that the sketch I made at the Yellowstone Lake Hotel remains the best of the bunch, even after I have done several studies now to arrange it into a finished piece.  I will keep at it.
On another note, I have been trying to make my own ground now, off and on, for several years but have finally stumbled onto a workable surface, I think.  It might be a life changing event.  Claret paper.  Not my own formula, but I did deviate from the recipe I was following.  I'll let you know how it turns out.
Claret Paper, in light blue and claret hues.  I will credit the original recipe after I test this to see how it works.
