I'll tell you why I no longer try to FMQ anything larger than a small twin at home.
Several years ago (when I was much younger, less achy, and more nimble than I am now) I pushed to get a quilt FMQ'd at home for a show and didn't want to pay for a LAQ rush job. For 8 weeks after that show, after quilting that quilt myself, I visited the chiropractor several times a week to "fix" the shoulder I'd "killed" trying to do it my self.
I could have paid the LAQ easily with the co-pays/deductibles I spent! Never again. I PROMISED myself.
