Work on a loom used to be (and still is) a slow and laborious process, requiring a lot of concentration and manual skills. Initially, weaving was concentrated mainly in the poor parts of the country and often was the main source of income. Weaving was previously operated mainly in highland areas, because flax and hemp would be grown there. Flax is harvested, soaked, dried, combed out, then spun on a spinning wheel into continuus thread - and then the working on the loom can begin. Textile is further proccesed after removing from the loom, namely: washing, bleaching and dyeing. Vegetable dyes were used by our ancestors since time immemorial. Traditional use of certain dyes survives today – such as the traditional Easter eggs dyed with onion skins or nettle leaves to grey-green colour. Blueprint is dyeing technique that comes from Wallachia. It preserves the tradition of natural dyeing by extracting the colouring from a plant called true indigo.
