The main cloth used in ancient Greek clothing was wool.
First the wool was soaked in hot water to rinse off some of the grease. Only affluent people would dye the wool due to it being an expensive process.
Greeks used different natural materials to produce the dye for their clothing: for brown dye they used oak bark; for pink, roots of the herb madder; for yellow, stalks of weld; and for blue, dried wood leaves.
After these processes were complete, they spun wool into yarn using a large loom.
We at Nisos 1948 have revived the same natural dyeing tradition for all our fabrics.
