Torchon lace is one of the most common forms of bobbin lace, and perhaps also the simplest. Ground and motifs are made at the same time, in strips of 2.5 to 5 cm wide. Use is made of a relatively thick thread. The motifs are simple. It is a strong type of lace originally made of linen, but cotton is also being used. The motifs are often outlined with a gimp thread. Originally hand-made, torchon lace is machine made since at least the early twentieth century.
