This is another one of those "it depends" questions. I like warm and natural or warm and white. Have tried Hobbs 80/20 and it is OK. I still need to do a whole quilt with the Hobbs to form a more informed opinion.
There are so many options, I think you need to try a few and see what works best for you. Also, it is sometimes desirable to change the batting up depending on the purpose of the quilt, whether it will be hand-quilted or machine quilted, whether it is used in the frozen NOrth or the balmy South.......
Like I said: It depends.....
