Plant milk and avocado

Left and above: Paint or soak paper in plant milk (such as soya). Allow to dry before dipping or soaking in the avocado dye. Make avocado dye by scraping all the green flesh off 2-3 avocado skins and pits and allow to dry for at least 2-3 days. Add water, boil and soak. (You may want to separate the pits and skins for varying shades) Leave overnight to steep. For a darker stain, add a glug of ammonia.
