I have just finished a very large quilt for my King size bed, I quilted the 12 large appliqued blocks then I stippled around the blocks and the sashing,leaving a small amount to add the outer edge parts, then I added the 20 inch drop all around the edge of the quilt,quilting and stippling , it was not that hard , I have an Aurora 440 machine , same size as my old 930 Bernina from many years ago, First I layed the backing out on the dining room table and pinned it together with the batting and the 12 blocks that had been sewn together, the batting was very thin, I think that is part of the answer to doing a large quilt on a regular sewing machine, I had the dining room table pulled up close to the machine to carry the bulk of the quilt as I quilted it ,(B.E.G.) My sewing machine is set up in a horne cabinet in the kitchen , it has a drop leaf along the back of the machine , so I pull it out from the wall and it gives me lots of support behind the machine ,No room to eat but who cares!!! I did roll the quilt and started the quilting in the center blocks from the center sashing out to the edge , then I quilted the blocks the same way . As I quilted the roll got smaller,After I quilted the center area I added the backing added batting sewing it to the other batting with a basting stitch to hold it together, then I added the top .The top and bottom edges were added with right sides facing each other for the first part, then I pinned them down and quilted all around the quilt , in the ditch for the borders, then finished up with stippling , then adding the binding.Planning on making a large wall hanging to go with it , Southwest with pots and beads, to hang over the head of the bed, So experiment and for petes sake have fun,
