I know what you mean, I have quilted quite a few big quilts - queen, king and it is a challenge. I have found that I have to pull my sewing machine out (on a table) a little ways so the quilt has room to drape over the side. I put a chair on each side and that works for me. You may not have that much room but this how I handle it. I too have said I am not doing big quilts anymore but this one snuck in as I need a spread for our queen size bed and I want it to cover the mattress and box spring, so it is nearly to the floor. I am using a lot of my fabric as I need to downsize. I just am not into quilting as much as I used to. I am 78 years old and maybe that comes with age. There are other activities I have also lost interest in. So goes life.
