I took an old 140 lb. cold pressed watercolor painting I had started and never finished and made an accordion sketchbook out of it. I covered some mat board with some decorative paper and ribbon for the cover. It measures 4 by 3 3/4 inches when folded up. Not quite square, but close enough.
I did a few drawings in it and set it aside.
I started carrying it with me lately and, as happens, I filled it! A little and often really does work.
Cold pressed watercolor paper has a slight tooth, not as much as rough paper, but sometimes it can be difficult to draw on with pen and ink. I found I like the way a Pilot V Razor Point pen works on this paper. It has the wonderful quality of not being waterproof and makes lovely washes. I touched the ink lines with a Niji waterbrush and the ink ran and made these lovely shadows and tones.
I drew where ever I happened to be and often didn't have time to complete some drawings. I like the way one blends into another when I unfold the sketchbook.
Having a sketchbook with me at all times is a great way to use those spaces in my day when I'm waiting for someone or I'm a little early for an appointment.
I actually look forward to these moments to do a little observing and drawing.
And I think I found a use for that stack of unfinished paintings I've had for quite a while now.
