I am researching Constructive Textiles and am interested in African Mud Cloth (Bogolanfini : pronounced "Bo-ho-lahn-FEE-nee") Mud cloth is woven in strips which are then sewn together making a larger piece of fabric which will be used for clothes or rugs. It is coloured by first using a 'tea' made from the bark of a local tree, the Bogolon, which gives an ochre colour and also acts as a fixative (mordant), the dark brown colour comes from mud (hence the name)with a high iron content. This is applied and sun dried on the cloth before washing. This process is repeated to intensify the colour to a dark brown. Further marks are made by using bleach to remove these colours and reveal the original neutral colour of the woven cloth.
