100% cotton cloth with a smooth weave in a creamy off white. This fabric is thick enough that you stitches won't show through from the back. It will make a beautiful background for an embroidered hanging.
If you want a fabric that can be used for visible mending or slow stitching, this is a strong fabric that can stand the washing and wear after stitching.
Size is 35cmx52cm (approx. 14"x20")
I have included a photograph here of several other good stitching fabrics available.
