Creative ideas to explore
Creative directions, not tested formulas.Woods in daylight
With bergamot and a crisp citrus openingExplore a spare wood structure with citrus providing the opening contrast. Compare a brighter version with the wood reference and follow how the outline changes, keeping the later impression as important as the first moment.
A softer grain
With sandalwood and a musk directionSet the woody material beside a softer wood reference, then compare a restrained musk variation. Decide whether your concept needs creamy texture, dry definition or more space between its parts before expanding the accord.
Petals on timber
With rose and a clear floral accordTry a flower-and-wood study in which both subjects remain recognisable. Compare the floral reference with the woody variation through the evaluation, noting whether the wood forms a useful backdrop or becomes the centre of the idea.
