Six attempts to sketch translucency using a range of line thicknesses; from ‘barely there’ (the pencil on the green San Pelegrino), to ‘bold’ (1mm Pigma pen on the chair with pint glass). They’re all late evening sketches of whatever’s in front of me, to keep up the daily drawing habit.

In the pint glass above there’s no ink/paint where the water ‘is’, but my brain can’t help seeing water there; the lines around it provoke a form of closure, the irresistible urge to complete a partial image or implied pattern. The highlights and shading tell me water should be there, so it is! I think closure can make sketches more engaging and satisfying than highly finished pictures and photographs; the viewer completes the image.

All sorts of mark-makers, Lexington grey ink water-brush for most of the shading, watercolour, A7 to A5 – 10-30 minutes each
