And What About a Dirty Pot
A dirty pot is usually maintained out of doors. It is a slow eco print method for gaining not so precise images and can be added to indefinitely until the water starts to go sour. I have used an old aluminium jam pan which is probably not the best option as the aluminium may alter the colours gained. The fabric is bundled - often with more foliage and maybe some rusty iron pieces and placed in the pot and simmered for an indefinite length of time. The bundles are often not as precise as in the steaming method as the object is to cover the fabric with natural dyes in a random fashion.
Below I show you two examples from the dirty pot of animal fibres - one with the traditional bundling technique and one with a random bundling or wrapping of the fabric around items to cover the surface of the fabric
