The Indigo Kit is the one that began it all, and is still by far the most popular offered by The Love of Colour, a small batch maker based in Toronto, Canada.
Contains the pre-measured ingredients to create one organic indigo vat, with which you can dye fabric, yarn, garments, home goods and more in gorgeous shades of blue. 
The indigo is 100% plant based and the process is nothing short of magical, as you watch the fibres turn from green to blue as they oxidize. 
Comes with detailed instructions aimed at an absolute beginner, which guide the user step by step.
Packaged in a sturdy, recyclable kraft paper box which has been silk screened by hand, they are graphic and giftable.
