How about flannel for the backing? I presume the quilt is cotton, but my guild friends say you can mix cotton and flannel... Haven't done that yet, but maybe someone else on the board can clarify this for us. Good luck!
I made a quilt for our youngest daughter, tied it rather, and used high-loft batting. She said I was really warm, and they al loved that quilt. It was pretty; I just didn't like it. Mariah
