Tambour is the French word for drum and tambour work is embroidery done with a hook where the fabric must be stretched tight as a drum. The fabric is stretched and laced or sewn on on a rectangular frame or in a circular frame. A tambour hook makes one stitch, the chain stitch. The hook is held on top of the frame with the threaded beads or sequins underneath.
Tambour work reportedly arrived in France in the 1720s from China. And it has a long history in India.
