Answer
Sadu is a Saudi Bedouin weaving craft built on repeating geometric patterns in red, black, white and brown, inscribed by UNESCO on the list of intangible cultural heritage. Its patterns appear in national designs because they are an authentically Saudi visual identity rather than an imported one. The tool includes six Sadu-inspired frames in emerald, aubergine, madder, teal, sand and night, for anyone wanting a heritage character instead of plain green.
