I don't do large quilts because I find them too hard to handle on my home machine even tho it has a larger throat/bed than most machines. It is hot to have on my lap / draped over my arms or shoulders, it aggravates my neck where I have degenerative disc disease/osteoarthritis and cervical herniated disc.
When I win that ever-illusive lottery, I will get a long arm machine!
