Tacking thread Fil Au Chinois

Tacking thread, as the name indicates, is used for tacking together different pieces of fabric before sewing them together definitively. Traditionally, the colour of the tacking thread is in stark contrast to the colour of the fabric, making it easy to see and remove.
Fil Au Chinois tacking thread is available in 6 colours. As it breaks so easily, it should not be used for sewing purposed other than tacking.
