All Harris Tweed is hand woven on a treadle loom at each weaver's home on a 'double-width' Bonas-Griffith rapier loom in the case of mill weavers, or normally an older 'single width' Hattersley loom in the case of independent weavers. The weaver will 'tie in' their warp by threading each end of yarn through the eyelets of their loom's heddles in a specific order then begins to weave, fixing any mistakes or breakages that occur until completed. The tweed then returns to the mill in its 'greasy state' and here it passes through the hands of darners who correct any flaws. Once ready the cloth is finished.
