If you’ve not met one before, a concertina sketchbook has one long zigzag page that folds up between the covers. How many pages it has and what type of paper depends on the brand; the one I’m using in this video is from Seawhite and slips into a case. (If you don’t see the video below, click here to go to my Vimeo channel.)
I started with Payne’s grey acrylic ink, then watercolour in a dropper bottle (including two granulating greens), watercolour from my set using a brush, acrylic paint (cadmiun yellow light and medium), a mixed blue-grey acrylic ink (the masking tape on the bottle tells me it’s a colour I’ve mixed), white acrylic ink (Sennelier’s super-opaque white), and ultimately a touch of orange acrylic ink to deepen the yellows in the flower centres.
The decision as to how many pages to do was intuitive, a feeling for how many would be manageable across the width of my table (and off a bit) and would probably not be totally dry by the time I got back to the start with a new colour. I’m drawing daisies from a mixture of memory and the ones in the jug in front of me, which I turned around at various points so I was seeing ‘new’ daisies.
The colours initially are a bit gloomy, but when I add the bright green these become “background shadows” and everything turns brighter. I had visualised this brighter layer of green before I started, I just didn’t know exactly when I would do it. I’ve got a list in my mind of what layers I’m going to do (colours/materials) but if you’re new to working like this it’s worth taking the time to draw up a list, and having everything to hand, so when you’re painting the decisions are already made and you can concentrate on painting.
What will I do with the rest of the pages? At the moment my thought is to continue with flowers, probably the pink foxgloves that are flowering now too, but I’ll see what I feel like when I start again.
This is only the second concertina sketchbook I’ve used; the first has a watercolour of the sea/weather from my studio on every pair of pages, with a consistent positioning of the horizon line across the pages (drawn in with a pencil before I started). I’m sure there will be more, not least because I have a little Sennelier one with thicker paper I won in a competition and the Moleskine one the in-house art critic gave me last Christmas to try.
