Antwerp lace is a bobbin lace distinguished by stylized flower pot motifs on a six point star ground. It originated in Antwerp, where in the 17th century an estimated 50% of the population of Antwerp was involved in lace making. Antwerp lace is also known, from its familiar repeated motif, as Pot Lace— in Dutch Pottenkant or Potten Kant. It is sometimes said that the flowers were a depiction of the Annunciation lilies; however, the flowers were not limited to lilies. It is a continuous lace, meaning that it was made in one piece on a lace pillow, using the same threads in the pattern as in the ground, or réseau. Antwerp lace is very similar to Mechlin lace, which was also made in Antwerp. Antwerp lace is heavier and sturdier than Mechlin lace. It has a cordonnet, or a flat thread outlining the pattern, just as Mechlin lace does. The cordonnet was very strong and rather coarse. Antwerp lace was also similar to Binche lace in its cordonnet. The réseau or ground for Antwerp lace varies from the same hexagonal ground as Mechlin lace to a tessellation-pattern featuring a six-pointed star.
