Opus Anglicanum or English work is fine needlework of Medieval England done for ecclesiastical or secular use on clothing, hangings or other textiles, often using gold and silver threads on rich velvet or linen grounds. Such English embroidery was in great demand across Europe, particularly from the late 12th to mid-14th centuries and was a luxury product often used for diplomatic gifts.
