I like Warm and White and Hobbs 80-20. I have also used fusible and generally like it -- just a word of advice don't iron it to flatten it and don't wash it.
I forgot I was working with fusible and tried to iron it because it was pretty wrinkled and -- you guessed it I glued the iron to the batting and the batting to the ironing board. It's funny now. If you prewash the fusing stuff washes out, so that is not good either.
