Mistake is my middle name. I'm always making mistakes even when I measure twice and cut once. Just yesterday I tried to squeeze a 19.5 quilt design into a 12.5 size space. I even stitched it out and went on to the next design. It wasn't until I went to the opposite side that I realized my mistake so yes, I stood over the frame for a couple hours frogging all the stitches out and stitching it over with the correct pattern. Sometimes having robotics is not a good thing as it will do whatever you tell it to do.........DUH!!!!! Sure glad I caught it before I put the next section on though. I think I'm the Queen of the Frogging Department.............:-(
