Reticella

Reticella (also reticello or in French point coupé or point couppe) is a needle lace dating from the 15th century and remaining popular into the first quarter of the 17th century.

Reticella was originally a form of cutwork in which threads were pulled from linen fabric to make a "grid" on which the pattern was stitched, primarily using buttonhole stitch. Later reticella used a grid made of thread rather than a fabric ground. Both methods resulted in a characteristic geometric design of squares and circles with various arched or scalloped borders.
