I don't think a brand was stated Anna, just solid black but that's what I normally use. I had ordered some Moda black to see the difference but don't think I will buy it again. Sure is a thinner weight fabric than Kona and found after doing these blocks I'd rather sew with Kona cotton. Lesson learned for me. Did the same thing with the white and don't like it as well either. Going to go to the Craftsy site today and order both colors while they have the 4 yd. cuts on sale.
