I love warm and natural and I have discovered I love the glue basting too. Only one layer of W&N will do the trick. It is thinner but it is so so warm with the single layer. Two layers really is to warm. I discovered that with the first quilt I did with W&N as I too thought it was to thin. What it does with a quilt is so different. The finished project is so smooth. Less puffy for sure but a nicer end product. I still use some polyester batts for a few things but have been spoiled bye W&N.
