There is a mid-arm set up at our LQS that we do our Community quilts on. It works and does get the job done but it would be nice not to have to stop and roll after one pass down and one back. It's a Husqvarna machine and usually takes about 6 bobbins to finish a twin size quilt using an overall stipple or meander. More space and a larger bobbin would work much better for us.
