You’ll need: a heat source, a metal pot (ideally with a lid), a spoon for stirring, a sieve, a muslin cloth for straining and a large bowl, and rubber gloves. To make the geometric pattern on the cloth, you'll need a pair of wooden coasters (or other shapes) and a metal clamp. To prepare your fibres before dyeing, you can either use soy(a) milk on plant fibres. For silk, the recipe uses alum, which will require a large pot or bucket to soak your fibres. For the soya milk method, you also need a bucket to soak your fabric. The indigo recipe requires some specific ingredients. You'll need indigo pigment powder, fructose and calcium hydroxide (lime). These are all easily available to buy online, and from natural dye supply shops such as Botanical Colors in the US, and Wild Colours in the UK. This is the equipment you'll need to make the indigo vat (it will seem much simpler once you watch the video). Try to repurpose old things you have lying around, and also thrift some secondhand tools: Three glass jars, spoons, digital kitchen scales, dust mask, goggles, a jug, a plastic bottle & marbles (to mix the indigo with water), a small funnel (or make one with paper), a large stainless steel pot and a stove for heating (or a plastic bucket and an immersion water heater), and an extra bucket to rinse fabric.
