That is a great idea, I dont' knwo why I didn't think of it! I mean, I do have a mid-arm in a frame that sits turned like that, why can't I turn my DSM on the sewing table to do smaller quilts? I have one of the acrylic bed extenders, too, so it would make perfect sense!
Funny how it sometimes takes someone else's question to make you realize you've already got the answer to your frustrations. =)
