Square brush, not sable
Used flat and bright bristle brushes — square-ended, stiff, broad — and applied paint in distinct interlocking mosaic-like blocks. Refused fine sables that would blend strokes into a glass finish.
Why it matters · The brush you reach for makes the painting before any decision about subject. A flat bristle holds more paint, deposits it in a single committed mark, and refuses the small fussy correction. Painters who reach for a tiny round end up overworking edges they would otherwise leave alone.

Grayed-green flesh underpaint
Underpainted his flesh tones in grayed greens, then layered warmer pinks and yellows over them — letting the cool underpaint show through and creating optical luminosity by contrast.
Why it matters · A pink put on a pink ground reads dull. A pink put on a green ground sings. Waterhouse's discipline was to underpaint cool and finish warm — the opposite of the intuitive instinct. Most painters reverse it and end up with flat dead skin.

Always start with the central female figure
Anchored the composition on the geometry of the central figure's body before resolving anything else — pose, weight distribution, fall of light on the cheekbone established first.
Why it matters · The figure is the carrying structure. Painters who block in environment first then "drop a figure in" produce paintings that float. The figure has to be load-bearing from the first sketch.
Oil comps before the big canvas
Painted small oil studies ("comps") to resolve color palette and atmospheric square-brush handling before committing to the full-scale exhibition canvas. Often painted a study for one painting on the front of a board and another on the back.
Why it matters · A small oil sketch is the only place to learn whether your color reads at scale before you spend two months on the wall canvas. Skipping the comp is the most expensive shortcut a painter can take.

Sculptor-trained spatial weight
Entered the Royal Academy Schools in 1870 as a sculpture probationer. Switched to painting only in 1874 — but the four years of sculpture trained the volumetric understanding visible in every painted figure.
Why it matters · A figure painter who cannot sculpt has trouble making a body weigh something on the canvas. The sculpture-first training is rare and valuable. Even one term of clay study before painting reshapes how a painter thinks about mass.
