My machine has a 10 inch throat and that helps very much.
I bought a Flynn frame and that was a mistake.
It is fine for baby quilts but nothing larger. It gets unmanageable when you add length to it and the balancing pvc pipe wants to fall off the table.
And you have to contend with all the length of your quilt being on one side of your machine when you reach the end. I dont have that kind of room to maneuver.
I have heard bad reports on the Fabric Mover also, because of the edge of the hole getting in the way.
I would very much like to have a stitch regulator but I dont have a Bernina.
So I only make up to lap size and sent out to a longarmer for anything larger.
I have seen demos of other frames that fit a regular sewing machine from the front end but it still is a financial risk. Maybe someone else has one and can give a report.
