I use a Bernina 1080. I made two sofa size quilts on it this past year. When I go to the quilt show in Virginia, I am going to get John Flynn's frame. It works with regular sewing machines. I have seen it demonstrated for years at the quilt show and decide that this year, one will come home with me. I am hoping that this will make it easier to do big quilts. My son and DIL have a king size bed and I still may have to do it in sections but it should be easier and quicker than all hand stitching.
