For my next quilt I am getting it basted by a long armer using water soluble thread! I don't have a place big enough to even put a queen or king sized quilt except on the floor, and I just can't crawl around on the floor any more. My sit down quilter does fine with the big quilts when I get it on the machine, but I just won't sandwich one ever again. A friend does long arm work, and she is willing to just do a simple grid every 3-4 inches. The tension doesn't have to be perfect, just enough to hold the quilt together. I have seen other long armers that advertise basting services too. I really like quilting my quilts myself, just to make them wholly mine. I don't feel the same attachment to sandwiching <grin>.
