This is a single mesh canvas which means it is woven with a single thread.
The threads are woven over and under each other in a typical weaving pattern and held together at the junction by sizing (starch). Mono blank needlepoint canvas is a good choice for stitching projects that are going to be used as furnishings, such as chair cushions. The mono canvas will "give" at the junctions rather than break under wear and tear conditions.
