Cotton batting like Hobbs 80/20 or, the 100% cotton is not difficult to hand quilt, there are many wonderful cotton battings that do not have scrim.

Battings with scrim allow a larger distance between quilting lines and hold up to the rough handling they go through with machine quilting. Mountain Mist, Fairfield and Hobbs are 3 of the companies that offer cotton batting for hand quilters
