i have quilted king-size quilts. just roll up the fabric on in inner side and squish it through. it is quite a production but it really isn't any more difficult than quilting a double. it is quite heavier so you will need a large table to hold all the quilt to your left. the quilt i did was a wedding quilt for my daughter and her hub. i would rather make the whole quilt from start to finish rather than have someone else do the work. plus, i don't want to spend money on that, rather spend it on fabric!!! if you use cotton batting like warm and natural, the quilt top and back "sticks" to the batting more so than the poly blends, so that helps with the not bunching part.
