i don't have one or need one, but i am curious and maybe someone can answer this: i read that post that was linked and it said there was a 4" quilting area. why is that? also, i think it would be hard to keep rolling and unrolling on that particular frame for a quilt of that size [50 x something]. is it much easier than making that size without a frame by rolling it up from both ends and starting in the center? i've seen it in the shows, but i never wrapped my head around it. he used it so fast, i couldn't keep up with how it technically worked and rolled, and there's always a crowd around anyone demonstrating anything, and you can't get a good look.
