I dye yarns and fibres with indigo, queen of blues. It produces fabulously varied shade variations beloved by many. But I also dye or overdye my yarns with acid dyes which increases the colour range.
An ancient dye, it has been used since at least 2500 BC. Most continents have native plants that produce indigo. It is sustainable; the plant residue is composted and the water reused to irrigate crops.  
Most natural indigo dye for sale comes from the leaves of Indigofera tinctoria which grows best in the heat of the tropics. It is light-fast and, unlike most natural dyes, does not need mordanted first.  
Synthetic indigo is widely used, not only by huge denim mills but by artisans worldwide to produce reliable results. Chemically identical to natural indigo, it bonds in the same physical manner.
Indigo does not chemically bond to fibre, but creates a physical bond, expanding when exposed to oxygen and getting trapped within the fibre.
Blue hands are a normal feature of using indigo. All my yarns and fibres are well rinsed and dried but when you manipulate the indigo-dyed yarn as you wind it and knit it the last loose particles of dye are released. While the fibres are being handled they rub off on your hands. This is not a flaw. These large indigo particles cannot bond to lighter coloured fibres as you work and will simply wash away.
Blue on your hands or clothing can be removed with soap and water but bamboo and wood may stainindelibly.
 Please be aware that the nature of indigo and the method of dyeing I employ mean that there are NO indigo dyed batches - most skeins are individually dyed.
For orders of more than one skein of a type I will try to match them but that does not imply they will be identical. 
If this is important to you please check with me before ordering so that I can do my best to help.
I acid dye in 300gm batches but if you wish a larger quantity I will dye to order, usually at no extra cost.
