2nd entry for Sept 10, 2015

These are three 10-minute studies at top, a 15-minute one 2nd from the bottom and a 20-minute one at the bottom.
The top one is Pitt pen on Canson Recycled Sketch paper; the next two have a gray Pitt brush pen and Koh-I-Noor Negro pencil on Canson Drawing paper, and the lower two are just the Koh-I-Noor on Canson Drawing paper. All are 18 x 18". The now awkwardly named Negro pencil is like a cross between Conte crayon and a coloured pencil, but fairly soft. It comes as a 5.6 mm rod that fits a bulky pencil holder, and is a bit brittle to use without the holder.
