My sewing machine has been "fixed", if that's what the lady did at the Bernina store. She basically told me I was being a baby and not to be afraid to push my machine around a bit. It wasn't going to bite me or break under my 3rd-grader-sized hands. I suppose that was a relief.
I've been practicing my roll-hem foot tonight before I finish up my blouse. As you can plainly see I need more practice. Anna Sui silk doesn't deserve these finishes.
