The name "leavers" derives from the loom used to create this lace. These ancient looms were originally manufactured in England in the 19th Century and afterwards introduced in Calais, France, where the highest production of precious laces still happens today. Because of the extremely complex and costly manufacturing process involved, leavers looms have no longer been produced since the early 1900s. La Perla is now preserving this extremely valuable heritage. Leavers looms are the only machines capable of working with a high number of threads, reproducing the intricate work of hand made lace. The lace created is distinguished by high definition design. The length, width and the thinness may vary depending on the machine used.
