As I discussed in Monday mornings class; here are the suggested supplies list for our experimentation in drawing in reverse. The related drawing, above, was worked in this method.
Strathmore 500 Series 18x24, Assorted Tints drawing pad.
Vine or Willow Charcoal; just make sure that it is of a soft variety.
Stump(s); The tortillions are not suggested. However if you already have them instead of a stump, they will do.
White Charcoal and Black Charcoal Pencils; a few of each will do fine. I would suggest a 6B for the black charcoal pencil.
In addition to all your regular drawing materials, I.E. erasers, sharpeners and such.
Since I was delayed in posting this, I will ask that you have these materials by the October 3rd class. If you have any questions, feel free to ask me in class or via e-mail; firstname.lastname@example.org
