Here is my first cast drawing using the sight size method. The drawing is in pencil and took me three days to complete. Most drawing casts intended for that purpose are rather pricey, but I found some inexpensive sculptures at a company called Design Toscono http://www.designtoscano.com/ They had gray accents, but a can of matte white spray paint fixed that. I bought three casts for less than $150. This is a bust of Michelangelo. I also bought one of Julius Caesar and a small bust of Venus de Milo. I will post cast drawings as I complete them.
