Lace is an openwork piece of textile made from one or more threads without a pre-existing support, unlike embroidery that corresponds to the ornamentation of a pre-existing mounting. Only made by hand with a needle and a single thread, the Point d'Alençon is a rare needle lace. It consists of the invisible assembly of small elements whose execution follows about ten steps. The patterns kept in a register (photo) are at the origin of the first step. They give shape to a first artistic drawing that depicts the finished lace in white ink, followed by a technical drawing in red ink on tracing paper adapted to the technical representations to be implemented.
