Calais lace is not a marketing term. It is a specific textile produced on Leavers looms in the town of Calais in northern France, using a construction method that has not fundamentally changed since the early nineteenth century. We have used it at Mind Tech Lab Wave since our first collection in 2019, and the reason is straightforward: nothing else behaves the same way against skin.

The Leavers loom and why it matters

A Leavers loom produces lace by intertwining threads in multiple directions simultaneously, creating a structure that is stable in all directions without being rigid. Most machine-made lace is produced on a Raschel loom, which is faster and cheaper but creates a fabric that stretches primarily in one direction. The difference is immediately apparent when you hold both against a light source. Calais lace has a three-dimensional quality that Raschel lace does not.

How it feels against skin

The thread used in Calais lace is finer than in most commercial lace alternatives. The result is a fabric that lies flat against skin without the slight scratchiness that cheaper lace can produce at the edges. This matters particularly in lingerie, where the lace is often in contact with sensitive areas for extended periods. We apply our Calais lace by hand at the atelier, which allows us to control the tension at the seam and avoid the puckering that can occur with machine application.

Why it is more expensive

A Leavers loom produces approximately one metre of lace per hour. A Raschel loom produces the same amount in a few minutes. The cost difference is direct. Calais lace from a reputable mill costs roughly eight to twelve times more per metre than its commercial equivalent. At Mind Tech Lab Wave, the lace in a single Cote Bralette represents about 30 percent of the material cost of the piece.

How to identify it

Genuine Calais lace carries the IGP (Indication Geographique Protegee) designation, which means it was produced in the Calais-Caudry region on a Leavers loom. If a brand claims to use Calais lace but does not name the mill, it is worth asking. We source from a mill we have visited in person and can name on request.

How to care for it

Calais lace should be hand washed in cool water with a pH-neutral soap. Do not wring or twist. Lay flat to dry. The lace itself is more durable than it looks, but the thread can snag on rough surfaces, so store lace-trimmed pieces in a cotton bag rather than loose in a drawer.

We use Calais lace because it is the correct material for what we are making. There is no cheaper alternative that produces the same result. That is the whole explanation.
