Oh - one more thing! I looked at your picture (your quilt is beautiful by the way!) again and, do you have an extension table for your machine? I have a very inexpensive (try $100) sewing machine and quilt everything but King size quilts on it. The extension table which adds maybe, 5 or 6 inches to my sewing space makes a HUGE difference. It's more than possible to free motion without it, but it makes things much easier. Another option, is I bought an old cabinet that didn't have a sewing machine in it at a thrift store for $2. My dad built a little "cradle" (or shelf) in it to hold my machine so I could drop it in, and it would be flush with the table. I then butt that cabinet and table up to a dining room table for BIG quilts.
Here are a few pictures just to remind you there IS hope for a person who is motivated to do it, to quilt on their little domestic sewing machine...and it doesn't have to be a fancy two-thousand dollar one either!
