On a warm afternoon, the soft yellow looks almost illegally fresh. It is the sort of detail that makes people smile before they even work out what they are looking at. Hang it and a plain wall stops being plain: the room picks up a lighter, chattier tone, the kind you want near food, drink and people. It works above a drinks trolley, in a kitchen nook, beside a dining sideboard or along a short stretch of hallway. Keep the surrounding surfaces simple so the joke lands pale wood, glassware, a few stoneware jugs, linen. Skip anything heavy or serious right next to it, and avoid busy patterned wallpaper, which fights the loose linework and flattens the humour. As a canvas the off-white ground reads softly and matt, with no shine over the drawing.
