Interesting topic. I just tried Quilter's Dream 70/30 and did not like it. It was thick and stiff. So far I like the Hobbs 80/20 best of for cotton batting. I'm trying QD Request next. I honestly like Mountain Mist, because it's lightweight and puffy, but I know it doesn't hold up. I've used the QD Poly once, but it didn't have the same soft puffiness, and it was stiffer than I like. I made a note to try the Soft & Bright (thanks, Austinite!).
