I am in the same boat! I am finishing up a queen size and I wrestled and wrested with it, trying to "stitch in the ditch". So I did very little and ended up tying it. When I went back to my machine, it was like it was frozen and wouldn't sew. I finally did get it to sew, but the stiches aren't right. I think I bruised it with my wrestling!!!! I have a Bernette ("made by Bernina"). Maybe we can only do "rag quilts"? Be interested to see what others write.
