How to make Rhubarb Mordant
Discover a quietly ingenious way to prepare natural fibres for dyeing with rhubarb leaves as a mordant. This accessible guide walks you through simmering the leaves in water to extract the tannins and oxalic acid that help natural dyes take hold—especially on animal fibres such as wool, silk, alpaca, cashmere, and mohair.
Rooted in gentle experimentation and resourceful reuse (perhaps from a rhubarb plant you’ve already harvested), this project encourages a slow and thoughtful approach—loving your materials while using fewer synthetic aids.
