Going ever wetter, looser & vaguer, below is a recent example of sketchbook work. I’m using a Saunders Waterford green spine watercolour sketchbook (NOT surface). Every double page opens up flat which is a bonus when you want the work to drift across two pages. I’ve started adding acrylic ink and acrylic pens (Derwent do a lovely range of colours) to the watercolour, both for line work and for the interaction between the two mediums, which can be interestingly explosive/repulsive with some colours. For the watercolour I’ve used cadmium yellow, russian green (St Petersburg Watercolours) green gold and perylene green and blocked in some smaller areas of background with white gouache
