Patchwork thread cones 

Our Fil Au Chinois special thread for patchwork is a waxed thread which has been passed through a bath containing a mixture of starch, fish glue and beeswax. This makes the thread smooth and resistant, whilst also giving it a relative stiffness. It is fine on most sewing machines, but may not be suitable for certain cheaper, less powerful models. We recommend testing with a spool before investing in cones.
