W&N does not make a black batting. The only ones I am familiar with are Hobbs 80/20 in black and Quilters Dream black poly which drapes, handles and feels like Hobbs 80/20. It is low loft and dense compared to other Poly battings. Once a long time ago I got a very dark gray batting that was a higher loft polyester that handled and felt more like Hobbs Polydown. I am not aware of a 100% cotton black on the market.
