I quilt a queen sized quilt with a 17" square Q Snap frame that I held in my lap and it worked very well. Only a couple of things to mention...the frame is a bit tight to get the quilt snapped into and it can catch seams and stretch the fabric and also, I would not leave the quilt in the frame I.e. Only have it snapped in while quilting, otherwise it could and probably would distort your quilt. It was a good RV travel alternative to be able to quilt without my floor frame.
