Weld or Dyer’s weed has been used as a dyeplant for many centuries in the Mediterranean, Europe and North Africa. It has been a long time favourite yellow due to its intense colour which has excellent lightfastness. Dyeing: Use extract on previously mordanted fibre at 7-10% WOF.    All measures in dyeing are based on the weight of material to be dyed. This is known as the Weight Of Fibre (WOF). WOF gives a convenient way to state how much dyestuff is needed for a given shade, regardless of whether the dyer wants to colour a few yarns or several metres of fabric. The weight of dyestuff is expressed asa percentage of WOF.    For example, to dye a medium-red with madder, we would use 50% WOF. Hence, if we had a pound of cotton (450 g) we would need a half-pound (225 g) of madder.^
