I bought a big roll of Hobbs 80-20 batting in a roll at the beginning of the year. It is folded in half on the roll, so you can't just 'mount' it on the frame. (I have a Juki on a Gracie frame.) I do have it under my frame, though, so when I'm ready to quilt I roll off the right size piece and cut. It will definitely save you money if you can find a place to put it!
