In Sanganer, just south of Jaipur, the river once ran in the colours of the dyes. For centuries the block-printers here have carved wooden blocks by hand, one for each colour, and pressed them onto cotton in careful registration, entirely by eye.
A single length of block-printed cloth can take days. The carver cuts the motif into seasoned wood. The printer dips, aligns, strikes, lifts, and moves a hand's width along, thousands of times, so that the repeat looks continuous. Where two impressions meet imperfectly, you see the human being who made it.
The colours come from a dye pot, not a Pantone chip, which is why block-print softens rather than fades. Wash it, use it, let it age. A Sanganer razai or bedsheet only becomes more itself with time.
