Hello - waaaay over there to Norway Eva!
I use the Warm and Natural - it's thin and I just like the way it makes the quilt look. It also seems to quilt nicely, whether by machine or hand.
There are many battings out there and I did purchase a few samples to try out and see the difference but haven't gotten around to that yet. I have heard lots of people like the wool battings or the newish bamboo battings, but I do think they are more expensive. Whenever Joann's (fabric/craft store here), has a batting sale, I usually buy the Warm and Natural at the King size - buy one, get one free. By the time I use those 2 packages up, they go on sale again.

Hugs,
