Daniela hands you a tight bundle of cloth, dripping blue and orange, and nods at the knot with a grin. "Go on. Untie it. I never know what is inside until it opens. Neither does anyone. That is the best part. Slowly. Let the colours come out on their own." The dye is still wet and the river is warm. Drift up the bank, pick a bundle and tell me which colour you feel like. I will tie something to match.
