If you can get the hang of it you will be able to hand quilt faster than if you use the rocking motion.... I can quilt a king in about 30 days by just picking it up when I have a chance... I also do not do as much quilting on mine as she does in the video...
Last year I did do a queen in 9 days but I was working on it instead of doing other things... It was a log cabin,, I quilted around the ditch on the inside edge of the block and the inside of the center block of the quilt.. Nothing fancy on it and my finished block size was 8 inches...
