Filet lace (also known as Embroidery on Knotted Net, Lacis, Filet Brodé and Poinct Conté) is a needle lace created by darning on a ground of knotted net or netting.

Filet lace is a form of decorative netting and as such can be presumed to have derived at some point from the netmaking that a fishing community would require.

If we agree that the latin word filatorium (normally translated as Network) is being used to describe Filet lace then Jourdain (1904) quotes a reference to Exeter Cathedral possessing four pieces of Filet lace in 1327. Ingram (1922) states that there was a "cushion of net-work in St. Paul's Cathedral so[sic] early as 1295."

More evidence comes from the publication of a pattern book by Federico de Vinciolo in 1587 which contains approximately 60 patterns which are suitable for Filet lace.

As mentioned above Filet lace is created on a ground of knotted net. That ground can either be made by the lace maker or as of 2005 purchased commercially in either handmade or machine-made varieties.
