Line drawings make sketchbook work more accessible. They are quick and immediate, as in very little thinking and hanging around! I haven't my usual paraphernalia of materials around me at the moment such as paint and mixed-media, due to building works here at home, so they had to be packed away. But the direct use of line and mark-making using in my case a fountain pen (my favourite mark-making tool!), still means I'm working in my sketchbook, which is becoming more important as time goes by, I'm finding it's the only link to any creative practice right now and so keeping me thinking creatively and getting me drawing everyday too.
