I tried out a Tin Lizzie 18"'sit down and the stand up version. I liked the sit down one which would work if you don't have space for the quilt frame. I could do the sit down FMQ. I have a machine with an 11" throat, but these long arms are also taller, so you have more room to move your quilt. I'm shopping the idea, been thinking about it for over a year, still undecided which way to go.
