Dry Brush

This week in life drawing class we started using ink.  We used a brush full of (diluted) ink but with the tip dried off.  We only got as far as simple shadow -- all one value.  We used white acrylic paint to cover any lines we didn't like.  We did 4 drawings in this way -- they are below in order.  The first three are on cartridge paper and the fourth is on watercolour paper.  (And the photo shows a small vase that I brought from Switzerland for my mother holding down the paper.)  Next week we're to bring 3 pieces of watercolour paper that we've already painted over with acrylic paint.  I guess it should look like a sheet of coloured paper before we begin the drawing.
