A foiling technique that begins at a precise parting and selects very thin slices of hair on the foil, alternating with thicker slices left out, in order to produce a softly blended, sun-touched look is best described as:

Explanation

Weaving uses the tail of the comb to lift a very thin alternating selection of hair onto the foil, leaving an equal or thicker section out. The result is a fine, dimensional, soft-blend highlight, ideal for a sun-touched look. Slicing (option A) takes a single solid slice, producing thicker, higher-contrast stripes. Cap highlighting (option C) pulls strands through a perforated cap and produces a uniform pattern but is not foil-based. Balayage (option D) is freehand painting that is generally done without foil, and is also a different selection logic. California licensees perform color under CCR Title 16 §979.4.
