Blackwork is a very old form of embroidery. It can be traced back to the 14th and 15th Century in Spain. Catherine of Aragon brought it with her to England when she married Henry VIII.
It is a counted technique and so requires to be stitched on an evenweave fabric, either Aida or Linen Evenweave.
As the name suggests black threads were traditionally used for this technique but it can also be interesting to use coloured threads.
This class is aimed at complete beginners.
