We seem to be looking at the inside surface; from the holes/tears the top, darker part of the sett, with the tidy edge, looks like it got most abused, probably on the other side of the cloth.

A double-thickness patch for the top edge of a worn or torn kilt apron, or a repair on a piece of upholstery?
It actually looks to me like it had been folded into quarters since the crease on the left appears concave while the one on the right looks convex.

Though that may have just been the way it was stored, not a result of its original function.
