Working principles

How the wood holds the work

1
The cut comes before the colour
Every band is incised into hardwood first; the tukula red is rubbed in afterward, so the geometry survives even when the pigment wears thin.
2
Palm oil finishes, varnish never does
A matte hand-rubbed sheen deepens the calabash brown over decades — no plastic gloss, no sealed top coat to crack.
3
No two registers repeat by accident
Interlace, lozenge and chevron bands are sequenced like a phrase — the maker varies them so the eye keeps reading down the panel.
4
A box is a tool, then an heirloom
Made to hold camwood paste for the body, the same vessel is kept generations later for the depth of its worked surface alone.
