It is NOT easy period and especially on a lightweight Brother. It CAN be done but I sure wouldn't do it again. I have the whatever 6000 "quilting" machine and have done quite a few small things. Then I did just wavy, straight lines on one to cover the sofa and another for the loveseat.
Then I got a vintage Singer 201 to put in a cabinet I already had. Her name is Miss MAM and she will not be "pushed around" by any quilt :-)
And that Brother has been put away ever since. I will only need it as backup and for deco stitches.
