Hobbs 80/20 is just too thin for me when I've got a cotton top and backing. So I double batt for cotton backings. I doubled my batting with a minky backing, and it was very heavy. But it will sure keep someone warm. I feel like the Winline Simply Soft 80/20 is more consistent than the Hobbs 80/20. I'm OK with a single layer of Winline 80/20.
