Brussels lace is a type of pillow lace that originated in and around Brussels. The term "Brussels lace" has been broadly used for any lace from Brussels; however, the term strictly interpreted refers to bobbin lace, in which the pattern is made first, then the ground, or réseau, added, also using bobbin lace. Brussels lace is not to be confused with Brussels point, which is a type of needle lace, though is sometimes also called "Brussels lace".
Brussels lace is part lace. This is made in pieces, with the flowers and design made separate from the ground, unlike Mechlin lace or Valenciennes lace; because of this, the long threads that form the design always follow the curves of the pattern, whereas in bobbin laces made all at once, the threads are parallel to the length of the lace. Brussels lace is also distinguished by its réseau or background, the toilé or pattern, and the lack of a cordonnet outlining the pattern. The réseau is hexagonal, with four threads plaited four times on two sides, and two threads twisted twice on the remaining four sides. The toilé can be of two types, the standard woven texture like a piece of fabric, or a more open version with more of the appearance of a netted réseau. This allows for shading in the designs, an effect that was used more in the later designs. In Brussels lace, instead of a cordonnet, the pattern is edged with open stitches, which are then picked up to form the réseau.
Brussels lace is well known for its delicacy and beauty. Originally it was only made from the finest spun linen thread, which was spun in dark damp rooms to keep the thread from becoming too brittle. Only one ray of light was allowed into the room, and it was arranged so that it fell upon the thread. This fine thread is part of what prevented mechanizing the process of making Brussels lace, as well as the production of it in other regions, as it could not be bought anywhere else. It was also what made the lace so costly. Brussels lace cost more than Mechlin lace, and was in high demand in England and France.
Brussels lace started to be produced in the 15th century, and was first explicitly mentioned in England in a list of presents given to Princess Mary at New Years', 1543.
